Question

a coil of insulated copper wire is connected to a galvanometer. what will happen if a bar magnetism 1 pushed into the coil. 2 withdraw from inside the coil 3head stationary inside the coil

Answer 1

It produces Current throght them and detects galvanometer

Answer 2

Hey there!!!!

★ 1) the Galvanometer shows a deflection which means current is induced in the coil , due to the relative motion between coil and magnet

★2) the Galvanometer shows a deflection in opposite direction which means current is induced in opposite direction in this case is the direction of motion is in the opposite direction with respect to coil

★3)There is no deflection in Galvanometer as no current is induced in the coil there is relative motion between coil


Hope this helps u!!!
