To induce an e.m.f. in the coil

A coil having an area 2m^2 is placed in a magnetic field which changes from 1wb//m^2 to 4wb//m^2 in an interval of 2 second. The e.m.f. induced in the coil will be

Whenever the magnetic flux linked with a coil changes,then an induced e.m.f. is produced in the circuit. This e. m. f. lasts
