Changes: Magnetism

Latest revision as of 08:02, 13 April 2023

Magnetism was a physical phenomenon caused by magnetic fields, which were themselves caused by Electromagnetism. Something exhibiting magnetism was said to be magnetic or magnetized. If that was their primary function, they were called a magnet.

In nature

In nature, planets and moons might have magnetic fields. These could potentially be used taped into for an energy source. (TNG: "Final Mission", "The Host") The breakup of planet Psi 2000 was characterized by dramatic changes in its magnetic field, including at one point a four degree shift of the whole field. (TOS: "The Naked Time")

The rings of Saturn also caused some magnetic distortion, and magnetic force originated from the Questar M-17. (Star Trek)

The Murasaki 312 had magnetic potential. (TOS: "The Galileo Seven")

Magnetic storms were a hazardous phenomenon in space and on the surface of planets like Rigel XII. (TOS: "Where No Man Has Gone Before", "Mudd's Women", etc)

Solar flares might be indicated by large magnetic disturbances on the star surface. During the Dominion War, the crew of the IKS Rotarran was even able to directly trigger a devastating solar flare after locating a magnetic instability on a star and increasing its magnetic gradient. (TNG: "Relics": DS9: "Shadows and Symbols")

Ionised hydrogen might generate magnetic currents. Nucleonic particles such as those found in polaric fields were also highly magnetic, and if accumulated might even create a diomagnetic field. (ENT: "Cogenitor", "Similitude")

In 2266, an unidentified yellowish ore was found on Alfa 177, which was subsequently determined to be magnetic. Magnetic deposits were also present on the Torothan homeworld. (TOS: "The Enemy Within";ENT: "Desert Crossing")

Magnetic waves were present in the Parvenium system, and were surveyed by a Starfleet ship in 2368. Spatial rifts might also emit magnetic shock waves. (TNG: "The Inner Light"; DS9: "If Wishes Were Horses")

A negative magnetic corridor connected two universes, one of matter and one of anti-matter. (TOS: "The Alternative Factor")

At least one living magnetic organism was encountered, which was characterized by a magnetic flux pulsing almost like the beating of a heart. Furthermore, the non-corporeal Ux-Mal entity claimed at one point that their consciousness had been captured by the magnetic currents of Ux-Mal, though this was part of an elaborate lie. A Delta Quadrant space-dwelling lifeform was also capable of generating a strong magnetic field.

As a technology

Warp drive design

Magnetic technology was widely used in starship design, in particularly in feeding of matter and anti-matter into the warp core.

Generally, containing a volume of anti-matter might be done using a magnetic containment field or magnetic bottle, and transporting (as in beaming) it could be done in a magnetic vacuum field. (TNG: "11001001"; TOS: "That Which Survives", "The Immunity Syndrome")

The plasma flowing into the system was magnetic. (TNG: "Galaxy's Child"; DS9: "One Little Ship", etc.) Antimatter containment relied on magnetic fields utilizing magnetic flow. On Constitution-class ships, this was monitored using a magnetic force indicator. (TOS: "That Which Survives") Another key component in the containment of antimatter and prevention of warp core breaches was the magnetic interlock. (Star Trek: First Contact; DS9: "Our Man Bashir") The Intrepid-class also had magnetic interlocks at the warp core. The Galaxy-class featured magnetic capacitors on the matter and anti-matter injectors. One way of dealing with problems in the latter was resetting the magnetic fields through a magnetic quench. (TNG: "Hollow Pursuits") This class also featured magnetic coils, and magnetic seals at the antimatter chamber. (TNG: "Contagion") NX-class starships used magnetic constrictors to align the positron stream, and constrictors were also used in the Intrepid-class. (ENT: "Cold Front")

Containment and shielding

Due to being made out of feromagnetic material, Control's nanites could be defeated by magnetizing them which appeared to destroy the nanites. Spock magnetized the floor of a starship to defeat the nanites that came out of Kamran Gant's body (DIS: "Through the Valley of Shadows") while Philippa Georgiou later did the same thing using the USS Discovery's reaction cube to neutralize Control itself from where it was occupying Leland's body. (DIS: "Such Sweet Sorrow, Part 2")

Magnetic shields were occasionally deployed to block transporters from beaming someone in or out a certain area. Beaming through a shield was possible with a code. Such a setup was present at Rura Penthe in the 23rd century and at Aldea a century later. (Star Trek VI: The Undiscovered Country; TNG: "When The Bough Breaks")

Malurians were able to create magnetic barriers. (ENT: "Civilization")

Magnetic envelopes could be created, and even tweaked so that anti-neutrons could pass through it but anti-gravitons could not. (Star Trek IV: The Voyage Home)

Attachments and locks

Magnets might be used to attach things. For example, on Sovereign-class ships the deflector dish was attached to the ship using magnetic restrictors. (Star Trek: First Contact)

Doors were often magnetically sealed. Magnetic seals were already in use aboard Enterprise. The Amargosa observatory contained a magnetically-sealed hidden door. (DS9: "Civil Defense"; ENT: "Acquisition";Star Trek Generations)

Suliban helixes were aggregate structures comprised of vessels held in place by an interlocking system of magnetic seals. (ENT: "Broken Bow")

Gravity boots, also known as magnetic boots, used magnetism to allow people to operate in environments with magnetic variances. (ENT: "Anomaly (ENT)";Star Trek VI: The Undiscovered Country)

Other applications

In Federation starships, magnetic constrictors were present in the impulse thrusters of runabouts, and magnetic inducers in Type 15 shuttlepods. (DS9: "The Assignment";TNG: "Transfigurations")

Intrepid-class ships might use magnetic spindle bearings, and their bridge consoles contained magnetic relays, which if overloaded could cause the console to explore. (VOY: "Fair Trade", "Once Upon a Time")

The USS Raman contained a magnetic storage bay. (TNG: "Interface")

Holograms were illusions created by projections of light held in a magnetic containment field. (VOY: "Phage")

The slingshot effect depended upon seeking out the magnetic attraction of a sun. (TOS: "Tomorrow is Yesterday")

The pain bands in use on Sigma Draconis VI were speculated to use a kind of magnetic lock by Montgomery Scott. (TOS: "Spock's Brain")

22nd century Romulan mine locked onto targets using magnetic spikes. Two centuries later, Federation antimatter mines had magnetic targeting capabilities. (ENT: "Minefield")

Cobalt-fusion warheads as used by the Lysian Central Command utilized magnetic propulsion. (TNG: "Conundrum")

Lazarus claimed his species used magnetic communications satellites. (TOS: "The Alternative Factor")

Jem'Hadar fighters featured magnetic flux couplers. (DS9: "The Ship")

Magnetic devices could be used to control Dom-Jot balls and thus cheat in the game. (TNG: "Tapestry")

Magnetic leverage might be used to lift cargo along an orbital tether. (VOY: "Rise")

The Turkana IV Coalition, a cadre operating on turkana IV, gave their operatives magnetic implants to ensure their loyalty. (TNG: "Legacy")

Magnetism in scans

Magnetism could also be used as a sensor technique, through a magnetic sweep or a magnetic residual analysis. (TOS: "That Which Survives"; TNG: "The Cage") Magnetic signatures could be looked for to compare readings. Wiping a memory core with an microdyne coupler left a unique magnetic signature. (TNG: "Time's Arrow"; ENT: "Affliction")

However, "magnetic clutter" could make scans more difficult. (TNG: "Heart of Glory", "Future Imperfect")

The Talosian community on Talos IV was found by detecting the magnetic field of their underground generator. (TOS: "The Cage")

The Borg were found to leave distinctive magnetic resonance traces. This was a working theory of Lieutenant Commander Elizabeth Shelby and was confirmed on the site of the New Providence colony disaster. (TNG: "The Best of Both Worlds")

Runabout hulls were made out of metallic composites that interacted with magnetic fields, the magnetic deflection of which caused extremely weak magnetic resonance patterns, which were distinctive enough to locate a runabout. Such weak fields could be detected with a differential magnetometer, a device developed in 2369. (DS9: "Battle Lines")

In 2373, the ship's engineer of a D'deridex-class ship was ordered to intentionally slightly misalign one of the ship's nullifier cores, thus creating a small polarized magnetic distortion in space whenever the ship was in motion, making it detectable even though it was cloaked. (TNG: "Face Of The Enemy")

Figuratively

A person may have also figuratively been said to have had a magnetic personality. James T. Kirk described Khan Noonien Singh as such upon first meeting him. Some time later, Kirk later in noted in his log that the women Harcourt Mudd peddled in had a magnetic effect on the male members of his crew, including himself. This was later revealed to be the result of the Venus drug. (TOS: "Mudd's Women")

Captain Kathryn Janeway, role-playing as Queen Arachnia, once remarked that Doctor Chaotica could not possibly resist her magnetism. (VOY: "Shattered") Data also once claimed to have a magnetic personality, though only as a pun. (Star Trek Generations)

Other information

Spock wondered if the Metron force that captured the Enterprise in 2267 was gravimetric, magnetic or electronic in nature. (TOS: "Arena")

+'''Magnetism''' was a physical phenomenon caused by [[magnetic field]]s, which were themselves caused by [[Electromagnetism]]. Something exhibiting magnetism was said to be magnetic or magnetized. If that was their primary function, they were called a [[magnet]].
-'''Magnetism''' is a fundamental interaction in nature which affects moving [[electric]] charges.  A moving electric charge in a magnetic field will be deflected at a right angle to the field direction.  Moving electric charges in uniform magnetic fields traverse helical paths.  Magnetic fields themselves are generated by moving electric charges.  This is actually a relativistic effect.  All electric charges create electric fields.  [[Albert Einstein]]'s Theory of Special Relativity says that an electric field, when viewed from a moving reference frame, will look like a magnetic field.
+== In nature ==
-When many electric charges flow in the same direction, the result is an electric current.  Long current-carrying wires will produce a magnetic field in the shape of concentric circles around the wire.  A circularly shaped current-carrying wire will produce a field in a shape known as a dipole.  Spinning spheres of electric charge will likewise produce dipole-shaped fields.  Certain types of metals, including iron, nickel, and cobalt (all found abundantly on [[Earth]]), also exhibit magnetic fields, even when no current is passing through them.  This is an effect of [[quantum mechanics]].  Subatomic particles such as electrons possess an intrinsic and immutable spin.  Even though they have no size, they behave as spinning spheres of charge, and thus produce magnetic dipohl fields.  Normally these dipoles are oriented in random directions and tend to cancel out.  However, in magnetic materials all of these dipoles can be made to point in the same direction, thus resulting in a net magnetic field.

-Magnetic fields were used extensively on [[Federation]] [[starship]]s, most notably in the containment of [[antimatter]].  Federation-designed [[warp drive]] systems employed a [[magnetic containment field]] to contain anti-deuterium prior to its injection into the warp reactor.  This field confined the anti-deuterium nuclei to circular motion, thus preventing them from annihilating with any normal matter.  If a warp drive's magnetic field strength falled below a critical value, antimatter containment would be lost, resulting in the destruction of the starship. ({{TNG|11001001}})
