Question: In a region of uniform magnetic induction $B = {10^{ - 2}}\,tesla$, a circular coil of radius 30 cm and resistance $\pi ^2 ohm$ is rotated about an axis which is perpendicular to the direction of B and which forms a diameter of the coil. If the coil rotates at 200 rpm the amplitude of the alternating current induced in the coil is


1) $4\pi ^2 mA$
2) 30 mA
3) 6 mA
4) 200 mA
Solution: Explanation: No Explanation
