Question

There are two loops a and b placed coaxially along vertical line. Loop a is allowed to fall freely towards loop b. If constant current flowing in loop a,then find the direction of flow of induced current in loop b as seen from the bottom of loop b

Answer 1

As two show magnet field and when see in centre it will straight and it and magnetic field produced by current carrying straight wire depends inversely on the distance from it and the concentric circle representing the magnetic field around it would become larger and larger as we move away from the wire
