In figure a rectangular loop is being pulled to the right, away from the long straight wire carrying current I in the upward direction. The induced current in the loop is ____

Answer»

zero
in clockwise direction
in anticlockwise direction
None of the above

Solution :
The magnetic FIELD DUE to wire carrying current go into the plane of the loop shown by `ox` .
When the loop moves away, on right, from the wire the FLUX linked with it-decreases. Hence, EMF will be so induced as the increase the flux. This happen only when the induced emf is in clockwise direction.
