Does a superconductor expel a magnetic field?
As a superconducting material transitions into its superconducting state, it ejects internal magnetic fields. In that light, yes, a superconductor could be said to expel a magnetic field according to what is called the Meissner effect. A link can be found below.
Do magnets have glue in them?
Magnets do not have any glue in them.
How can magnets repel other magnets?
forever
Where are superconductors used?
SuperConductors are electrical conductors having zero resistance. Superconductivity is referred as a "macroscopic quantum phenomenon". Superconductivity is reached at extreme cold temperature close to absolute zero. SuperConducting material will repel a magnetic field. normally a magnet hovering over a conductor will induce electrical currents in that conductor, this induced current is an exact mirror of the field that would have otherwise penetrated the superconducting material causing the magnet to be repulsed. This phenomenon is known as strong diamagnetism also referred as the "Meissner effect". The Meissner effect is so strong that a magnet can actually be levitated over a superconductive material. Superconductivity has so many application fields, and we have just mentioned one, "The levitation", which can make trains float over the rails. Superconducting magnets will significantly reduce power consumption in contradictory to traditional electro-magnets - CERN projects are a good example that uses huge superconductivity to accelerate particles. Another application field is biomagnetism, like MRI (magnetic resonance imaging) and another commercial application is the electrical generators wounded with superconductive wires which operates far more efficiently than the generators with copper wires.SuperConductivity has unlimited benefits in many other domains, we may also manufacture superconducting cables to transfer commercial electricity to the cities or integrate superconductivity concept into microchips.
Which temperature of Magnets affects the magnets strength?
cold temperature affects the magnets strength by making it stronger
Why are superconductors used in strong magnets?
Superconducting magnets are electromagnets wound from superconducting coil (wire). Wire that conducts electricity with zero loss is said to be super conducting. At the present time zero resistance is not offered by any known material at room temperature, so superconducting magnets must be chilled to very low temperature.
What has the author Richard J Thome written?
Richard J. Thome has written: 'MHD and fusion magnets' -- subject(s): Magnetohydrodynamics, Superconducting magnets
Where are superconductive magnets made at?
Example of superconducting alloys: Nb-Ti, Nb-Sn, V-Ga.
How do you use alloy in a scientific sentence?
A steel alloy that contains titanium can withstand greater temperatures. A special alloy is used for superconducting magnets.
What is the main purpose of helium?
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
Why do you use helium to super-cool magnets and why not use liquid nitrogen?
Liquid nitrogen is not cold enough to supercool some superconducting magnets to make that magnet's superconductive properties emerge. It takes something like liquid helium to do that.
What are different words that involve magnets?
Electromagnet Superconducting magnet Ferromagnetic Magnetic needle Magnetic compass magnetic field. Hydro magnet Gyro magnet
Can you bring magnets on an airplane?
Small magnets should be fine, industrial strength magnets may cause problems in the cockpit
What has the author G J Gabriel written?
G. J Gabriel has written: 'Coupled wave model for large magnet coils' -- subject(s): Superconducting magnets, Electric coils
Why does then large hadron collider need helium?
Liquid helium is colder than anything else on the face of the Earth. They cool the magnets with helium so the wire they're made out of will superconduct - flow electricity with no resistance. The LHC's magnets use 1.5 million watts of power all tolled; imagine how much they would need if the wire had even a thousandth of an ohm per meter resistance!
What is a superconducting magnet?
A superconducting magnet is one that is made of material that exhibits the property of superconductivity.
Are there maglev trains that use repulsion to move?
Yes, the Japanese system uses magnets that attract, then repell the train.EDS - ElectroDynamic Suspension (Japan) - "pull, neutral, push" system. Superconducting magnets in the train are pulled forward by track magnets. When the train is over the track magnet the track switches to neutral, then to the opposite polarity. So the magnet behind the train then pushes it forward.
