Are the magnetic field lines closed? Explain.
The direction of magnetic field lines appears to be closed but we can’t say by just looking at the picture.
The Magnetic field lines always begin from the North ‘N’ pole of the magnet and end on south ‘S’ pole of the magnet.
However, inside the magnet, the direction of magnetic field lines is from ‘S’ pole to ‘N’ pole. Therefore the magnetic field lines are closed.
The figure below illustrates the magnetic field lines direction.
