An athlete peddles a stationary tricycle whose pedals are attached to a coil having 100 turns age of area `0.1 m^(2)`. The coil, line in the X-Y plane is rotated in this plane at the rate of 50 rpm about the Y-axis in a region where a uniform magnetic field `vec(B) = (0.01) k`, tesla is present. Find the
(i) maximumemf
(ii) average emf
generated in the call over one complete revolution.

Explanation

(i) The maximum emf `.epsilon.` generated in the coil is,
`epsilon = NBC omega`
`= NBA 2pi f`
`(because 50 rpm = (50)/(60) = (5)/(6)` revolution per sec)
`= [100 xx 0.01 xx 0.1 xx 2pi ((5))/(6)]`
`= (pi)/(6) = 0.52 V`
The average rmf generated in the coil over one complete revolution = 0
