Vedclass · Answer

(A) When a bar magnet is moved relative to a coil of insulated copper wire,the magnetic flux linked with the coil changes.According to Faraday's law of electromagnetic induction,this change in magnetic flux induces an electromotive force $(EMF)$ and consequently an electric current in the coil.When the bar magnet is pushed into the coil,the galvanometer needle deflects momentarily in a particular direction,indicating the presence of an induced current.
