Electricity Field Magnetic Magnetic field Superconductor

In summary, when electricity flows through a superconductor, it creates a persistent current which generates a magnetic field around the superconductor. This magnetic field can be controlled by adjusting the amount of electricity flowing through the superconductor. Unlike regular magnets, the magnetic field in a superconductor is not created by aligning magnetic domains, but rather by the flow of electricity. The applications of this magnetic field include magnetic levitation, high-speed transportation, and medical diagnostics such as MRI.

So since a lot of electricity ran through a coil creates a magnetic field as sown in one of faradays most famous experiment what if the coil was a superconductor and will it improve the magnetic field and will it make one at all?

Related to Can electricity in a superconductor make a magnetic field?

1. How does electricity in a superconductor produce a magnetic field?

When electricity flows through a superconductor, it creates a circulating current. This current, known as a persistent current, produces a magnetic field around the superconductor.

2. Can the strength of the magnetic field in a superconductor be controlled?

Yes, the strength of the magnetic field in a superconductor can be controlled by adjusting the amount of electricity flowing through it. The more current, the stronger the magnetic field.

3. Is the magnetic field in a superconductor always present?

No, the magnetic field in a superconductor is only present when there is a persistent current flowing through it. If the electricity is turned off, the magnetic field will disappear.

4. How is the magnetic field in a superconductor different from a regular magnet?

The magnetic field in a superconductor is different from a regular magnet because it is not created by aligning magnetic domains in a material. Instead, it is created by the flow of electricity through the superconductor.

5. What are the applications of the magnetic field produced by electricity in a superconductor?

The magnetic field produced by electricity in a superconductor has various applications, including magnetic levitation, high-speed transportation systems, and magnetic resonance imaging (MRI) in medical diagnostics.
