A wheel with 20 metallic spokes each 1 m long is rotated with a speed of 120 rpm in a plane perpendicular to a magnetic field of 0.4 G. The induced emf between the axle and rim of the wheel will be, (1 G = 10-4 T)
- \(2.51 \times 10^{-4} \mathrm{~V}\)
- \(2.51 \times 10^{-5} \mathrm{~V}\)
- \(4.0 \times 10^{-5} \mathrm{~V}\)
- 2.51 V
Answer
(B) 2.51 10^ -5 ~V
