Question

A non conducting ring of radius r and mass m has charge q moving with angular velocity 'w' then magnetic moment will be

Answer 1

Hey!! ☺

Here is your answer

_______________________

A thin, non-conducting ring of mass m, carrying a charge q, can rotate freely about the axis. At the instant t=0 the ring was at rest and no magnetic field was present. Then suddely a magnetic field B was set perpendicular to the plane. Find the angular velocity acquired by the ring. 3. The attempt at a solution
