A field of 0.2 tesla acts acts at right angles to a coil of area `100 cm ^(2)m` with 50 turns. The coil is removed from the field in 0.1s . Find the emf induced .

Magnetic field of 2 xx 10^(-2) Wb m^(2) is acting at right angle to a coil of 1000 cm^(2) having 50 turns. The coil is removed from the field in (1)/(10) second. Find the magnitude of induced e.m.f.

A field of 2xx10^(-2) T acts at right angles to a coil of 50 turns of area 1000 cm hat 2 . The coil is removed from the field in 0.1 second . Then the induced emf in the coil is __
