Question

A steady stream of electrons moves with constant speed
along the line AB which lies in the same plane as a
conducting circular loop of wire. The direction of
induced current, if any, in the loop is​

Answer 1

Answer:

Option d. No current is induced in the loop

Explanation:

For current to be induced in the loop there should be change in the flux through the loop. Since the loop isn't changing in area, the magnetic field must change through the loop.

But the constant velocity flowing electrons gives constant current meaning constant magnetic field through the loop.

So, by any case there's no change in the flux through the loop. Therefore no current is induced.
