A coil of insulated copper wire is connected to a galvanometer. What will happen if a bar magnet is
(i) pushed into the coil?

Open in App

Solution

(i) As magnet is moved, the magnitude of field (or number of magnetic field lines) passing through the coil changes and a current is induced inside the coil. So, the galvanometer needle gets deflected when the bar magnet is being moved.
