Figure-5.55 shows a small circular coil of area A suspended from a point O by a string of length l in a uniform magnetic induction B in a uniform magnetic induction B in horizontal direction. If the coil is set into oscillation like a simple pendulum by displacing it a small angle `0_(0)` as shown, find EMF induced in coil as a function of time. Assume the plane of coil is always in plane of string.

Answer

`(1)/(2)Ba theta_(0)^(2)sin(2sqrt((g)/(l)t))`
