A conducting loop of resistance R is pulled in a uniform magnetic field `vecB`, with uniform velocity `vecv` (see fig.). During this process it is found that …….

Options

A. the temperature of the loop remains constant
B. the temperature of the loop decreases
C. the temperature of the loop increases
D. none of these above.

Answer

C

Explanation

When a loop moves the flux associated with changes and hence induced current produced and due to the resistance of a loop `I^2Rt` heat energy produces, so the temperature of the coil increases.
