Wheel with 10 spokes each of length ‘L’ m is rotated with a uniform angular velocity 'ω' in a plane normal to the magnetic field ‘B’. The emf induced between the axle and the rim of the wheel.
(1) 1/2 ω BL2
(2) NωBL2
(3) 1/2 NωBL2
(4) ωBL2
Correct option (1) 1/2 ωBL2
Explanation:
Emf induced is independent of number of spokes.
