Electro Magnetic Induction And Alternating Currents Question 485
Question: A superconducting loop of radius R has self-inductance L. A uniform and constant magnetic field B is applied perpendicular to the plane of the loop. Initially current in this loop is zero. The loop is rotated by
Options:
A) zero
B)
C)
D)
Show Answer
Answer:
Correct Answer: C
Solution:
-
Flux can’t change in a superconducting loop.
Initially current was zero, so self-flux was zero.
