Practice Bihar Board Class 12 (BSEB) Electromagnetic Induction in the app →A bar magnet pushed into a coil at rest causes the galvanometer needle to kick because:A copper rod of length $0.5$ m slides at $4$ m/s perpendicular to a $0.2$ T field. The motional EMF is:A coil of self inductance $0.2$ H carries $5$ A. The magnetic energy stored is:A bar magnet falling into a vertical copper tube on the lab bench drops more slowly than in free fall because:
