Question

What is the magnitude of induced current in a circular loop KLMN of radius r if straight wire PQ carries a steady current of i amp?

Answer 1

The answer is 0 because for any current to be induced, it needs to have a change in flux. The wire carries a steady current so there will be no change in flux. Hence, current induced will be zero.

Answer 2

What is the magnitude of induced current in a circular loop KLMN of radius r, if straight wire PQ carries a steady current of i ampere?

=> Zero.

No current will be produced in the loop because the magnetic flux doesn't change or there is no relative motion between the magnetic field around the conductor & the circuit loop.
