Question

Two identical metallic square loops $L_{1}$ and $L_{2}$ are placed next to each other with their sides parallel on a smooth horizontal table. Loop $L_{1}$ is fixed and a current which increases as a function of time is passes through it. Then loop $L_{2}$ .

Solution

The correct option is D Moves away from $L_{1}$
When the current through $L_{1}$ increases then the flux in $L_{2}$ will increase, according to lenz law $L_{2}$ will start moving away from $L_{1}$ in order to counter the change in magnetic flux.
