1.

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 …….

Answer»

the TEMPERATURE of the LOOP remains constant
the temperature of the loop decreases
the temperature of the loop increases
none of these above.

Solution :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.
