A square loop of side L, resistance R placed in a uniform magnetic field B acting normally to the plane of the loop. If we attempt to pull it out of the field with a constant velocity v, then the power needed is

A rectangular loop of wire is placed in a uniform magnetic field B acting normally to the plane of the loop. If a man attempt to pull it out ofthefield with velocityv as shown in figure-5.338, calculate the power required for this purpose.

A square loop is placed in a uniform magnetic field vecB as shown in fig. The power needed to pull it out of the field with a velocity v is proportional to

A square loop MNOP of side 20 cm is placed horizontally in a uniform magnetic field acting vertically downwards as shown in Fig. The loop is pulled with a constant velocity of 20 cm//s till it goes out of the field.
