A car moves on a plane road. Induced e.m.f. across
the axle is maximum when it moves
(1) At the poles
(2) At equator
(3) Remains stationary
(4) No e.m.f. is induced at all

Emf induced:E=BLV sinθwhereB=Magnetic fieldL=lengthV=Velocityθ=Angle E=Emax when θ=90oAs θ=90o denotes poles, the correct option is 1
