Question

A wire loop is moving in a uniform magnetic field at a constant speed as shown in the following diagram. The arrow shows the direction of the motion. The motion does not induce any current in the loop. A possible reason could be...

(a) The loop is not moving at an acceleration

(b) The motion of the loop is not in the direction of the magnetic field

(c) There is no change in the magnetic flux in the loop

(d) The loop is too small

Explanation / Answer

(c) There is no change in the magnetic flux in the loop

since the loop is moving with the constant velocity, the area of the loop is not going to be changed at any time.

anyway the magenetic field is uniform. hence the magenetic flux linked with the loop remains constant therefore the induced emf is zero which is the rate of change of magenetic flux.

Therefore the no current in the loop
