QNEET-2022-Ph-442: NEET 2022 Physics - Class 12 NEET-2022-Ph-442 Solution: A big circular coil of 1000 turns and average radius 10 m is…

A big circular coil of 1000 turns and average radius 10 m is rotating about its horizontal diameter at 2 rad s−1s^{-1}. If the vertical component of earth's magnetic field at that place is 2×10−5 T2 \times 10^{-5}\ \text{T} and electrical resistance of the coil is 12.56 Ω\Omega then the maximum induced current in the coil will be 0.25 A 1.5 A 1 A 2 A
