Q. Assertion :In a varying magnetic field the induced currents exhibit diamagnetic-like repulsion effects. A conductive object will experience a repulsion force. Reason: Eddy currents produced in conductor will produce magnetic field to oppose the varying magnetic field according to faradays law

Q. Induced currents produced in a solid core placed in changing magnetic field are called eddy currents

Q. Assertion :Self-induced eddy currents are responsible for the skin effect in conductors.It cannot be used for non-destructive testing of materials for geometry features, like micro-cracks. Reason: By Lenz's law, an eddy current creates a magnetic field that opposes the magnetic field that created it, and thus eddy currents react back on the source of the magnetic field.
