Q. When a loop moves towards a stationary magnet with speed $v,$ the induced EMF in the loop is $E.$ If the magnet also moves away from the loop with the same speed then the EMF induced in the loop is:

Solution:

The magnetic flux passing through the loop is a function of distance between magnet and the loop. When magnet moves then rate of change of flux will be directly proportional to the speed of the magnet and if loop also moves away from the magnet then relative speed of hte two is zero and no EMF will be induced in the $100p$
