A wheel with 10 metallic spokes each 1.0 m long is rotated with a speed of 240 rev/min in a plane normal to magnetic field of 0.4 G at the place, the induced emf between the axle and the rim of the wheel is; Given that $1G=10^{-4} T$. |
$6.28×10^{-5} V$ $7.536×10^{-4}V$ $7.536×10^{-5} V$ $5×10^{-4} V$ |
$5×10^{-4} V$ |
The correct answer is Option (4) → $5×10^{-4} V$ |
