dB dt The magnetic flux density B is changing in magnitude at a constant rate of B A given mass m of copper drawn into a wire of radius a and formed into a circular loop of radius r is placed perpendicular to the field B The induced current in the loop is I The resistivity of copper is p and density is d then A i m dB 4 pd dt
