a small ring of radius r and mass m carrying a current g is

Question

a small ring of radius r and mass m carrying a current g is placed at the centre of large ring of mass M and radius R R>>>>r and carries a current f

initially the plane of the two rings are having plane perpendicular to each other and overlapping

if the smaller ring is disturbed slightly find the maximum angular velocity of the smaller ring
