Assertion :In a varying magnetic field the induced currents exhibit diamagnetic-like repulsion effects. A conductive object will experience a repulsion force. This can lift objects against gravity, though with continual power input to replace the energy dissipated by the eddy currents. Reason: Separation of aluminum cans from other metals in an eddy current separator is an application of eddy current.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
