A circular coil of radius 10 cm, 500 turns and resistance 2 `Omega` is placed with its plane perpendicular to the horizontal component of the earth’s magnetic field. It is rotated about its vertical diameter through `180^(@)` in 0.25 s. Estimate the magnitudes of the emf and current induced in the coil. Horizontal component of the earth’s magnetic field at the place is `3.0xx10^(–5) T`.
