Question

a conducting circular loop of radius r carries a constant current i. it is placed in a uniform magnetic field b such that b is perpendicular to plane of loop.the magnetic force acting on loop..

Answer 1

The net force on the loop will be zero because the loop is kept perpendicular to the uniform magnetic field.

Answer 2

A CONDUCTING CIRCULAR LOOP OF RADIUS r CARRIES CONSTANT CURRENT i .It is placed in a uniform magnetic field B such that B is perpendicular to the plane of the loop.the magnetic force acting on the loop is. ... But the current flows in opposite direction. Hence the forces cancel each other.
