JEE Mains Model Paper 12

A square loop of wire of side 5 cm is lying on a horizontal table. An electromagnet above and to one side of the loop is turned on, causing a uniform magnetic field downwards at an angle of 60° to the vertical as shown in the figure.

The magnetic induction is 0.50 T. The average induced emf in the loop, if the field increasesfrom zero to its final value in 0.2 s is ….
