Part A The armature of a small generator consists of a flat, square coil with 130 turns and sides with a length of 1.60 cm. The coil rotates in a magnetic field of 8.65x10-2 T What is the angular speed of the coil if the maximum emf produced is 2.80x10-2 V?

Explanation / Answer

Given,

Area, A = 0.162 = 2.56 x 10-4 m2

Emf produced, Emax = BANw

=> Angular velocity, w = Emax / BAN = (0.028)/(0.0865 x 2.56 x 10-4 x 130) = 9.73 rad/sec (Ans)
