Choose the correct statement(s) from the following :
The magnetic line e of forces is closed curves. They appear to converge or diverge at poles outside the magnet they run from north to south and inside from south to north.
Magnetic lines of force never intersect each other because if they do so there will be two directions of magnetic fields which is not possible.
A magnet attracts other substance through the phenomenon of magnetic induction. It is the process by which an object or material is magnetised by an external magnetic field.
