A magnet is held above a copper loop at tlvmn and then dropped What is the direction of the induced magnetic field magnet reaches point A? What is the direction of the included current ? What is the direction of the Induced magnetic field when the edge of the north pole of the magnet reaches point B? What is the direction of the induced current ?

Solution

(a). The direction of induced magnetic field is opposses the actual magnetic field(i.e., from north to south pole).So, direction of induced emf is from south pole to north pole.

The direction of induced current is clockwise direction.

(b).The direction of induced magnetic field is opposses the actual magnetic field(i.e., from north to south pole).So, direction of induced emf is from south pole to north pole.

The direction of induced current is counter clockwise direction.
