Rotating a superconducting loop
Electricity and Magnetism
Level
4
A superconducting (zero resistivity) loop of area \(A=10^{-2} m^2\) is placed in a constant magnetic field of induction \( B=10 mT\) so that its plane is parallel to the magnetic field. The ring is now rotated so that the magnetic field forms an angle of \(30^{\circ}\) with its plane. What will be the current in Amps in the loop after it is rotated if its inductance is \( L=1 \mu H\)?
