CUET Preparation Today
A coil of 400 turns of effective area $0.05\, m^2$ is kept perpendicular to a magnetic field of $5 × 10^{-3} T$. When the plane of coil is rotated by 90° around any of its co-planar axis in 0.2 s in magnetic field, the emf induced in the coil is |
0.2 V 0.05 V 0.1 V 0.5 V |
0.5 V |
The correct answer is Option (4) → 0.5 V |
