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. |

Answer» Solution :(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 |
