#Magnets can exert force from a distance.
It is a #non-contact force.
The region around the magnet where magnetism can be experienced is called #magnetic field.
#Properties of magnetic field #lines
1)The magnetic field lines never cross each other.
2) They emerge from north pole and enter into the south pole.
3) They form closed loops.
