A circular loop made of thin copper wire of mass 'm' is placed m a uniform magnetic field such that the plane of the loop is perpendicular to the magnetic field. If :d' and ‘ρ’ are thedensity and resistivity of copper respectively and the magnetic field varies at a constant rate of

, then the induced current in the loop is__________
