A strong bar magnet is placed vertically above a horizontal wooden board. The magnetic lines of force will be:
(a) only in horizontal plane around the magnet
(b) only in vertical plane around the magnet
(c) in horizontal as well as in vertical planes around the magnet
(d) in all the planes around the magnet
(d) in all planes around the magnet
Explanation
If a strong bar magnet is placed vertically above a horizontal wooden board, the magnetic lines of force will be along all planes around the magnet, because the magnetic field lines always begin from the N-pole of a magnet and end on the S-pole of the magnet. Hence, spread in all the planes.
