Two identical circular loops of metal wire are lying on a table without touching each other. Loop-A carries a current which increases with time. In response, the loop-B

Options

A. Remains stationary
B. is attracted by the loop-`A`
C. is repelled by the loop-`A`
D. rotates about its `CM`, with `Cm` fixed

Answer

C

Explanation

If the current increase with time in loop.`A`, then magnetic flux in `B` will increase. According to Lenz's law, loop-`B` is repelled by loop-`A`.
