Answer 2

The lines representing the magnetic field are called magnetic field lines.

Properties of Magnetic field lines:-

• Two magnetic field lines never intersect at a point.

• They are always arranged in the form of closed concentric circles outside the magnet and move from north to south.

• They are uniform, straight and parallel inside the magnet and move from south to north.

• They are denser and stronger near the poles and weaker when wider apart.
