By using $$e=$$−NBAcos⁡θ$$2$$−$$cos$$⁡θ$$1$$Δ$$te=$$−$$1000$$×$$2$$×$$10$$−$$5$$×$$500$$×$$10$$−$$4cos$$⁡$$180$$∘−$$cos$$⁡$$0$$∘$$0.2=10$$−$$2$$ volt $$=10mV$$

A coil has 1,000 turns and 500 cm² as its area. The plane of the coil is placed at right angles to a magnetic induction field of $2 \times 10^{- 5} Wb / m^{2}$ . The coil is rotated through 180^o in 0.2 seconds. The average e.m.f. induced in the coil, in milli-volts, is
