Question

A write loop is placed in a uniform magnetic field. Over a period of 2 s, the loop is shrunk. Which statement about the induced potential difference is correct? AO There will be no induced potential difference because the loop is shrinking. BO There will be no induced potential difference because the center of the loop is not moving. CO There will be no induced potential difference because the loop changes size along one axis and not the other. DO There will be some induced potential difference, because the center of the loop is moving. EO there will be some induced potential difference, because the area of the loop is changing.

Explanation / Answer

Here,

According to Lenz's law

If an induced current flows, its direction is always such that it will oppose the change which produced it.

as the magnetic flux is decreasing with time

the magnetic field due to induced current will be in same direction as the applied field

hence , the correct option is

E) There will be some induced potential difference ,because the area of the loop is changing
