An a.c. generator consists of a coil of 50 turns and area `2.5 m^(2)` rotating att an angular speed of `60 rad s^(-1)` in a uniform magnetic field B = 0.3 T between two fixed pole pieces. The resistance of the circuit including that of coil is `500 Omega`. Find (i) the max. current drawn from the generator.
(ii) What will be the orientaiton of the coil w.r.t. the magnetic field to have (a) maximum (b) zero magnetic flux ?
(iii) Would the generator work if the coil were stationary and instead, the pole pieces rotated together with the same speed as above ?
