List the properties of magnetic lines of force

Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet.

The properties of magnetic lines of force are as follows.

• Magnetic field lines emerge from the north pole and merge at the south pole.
• As the distance between the poles increases, the density of magnetic lines decreases.
• The direction of field lines inside the magnet is from the South Pole to the North Pole.
• Magnetic lines do not intersect with each other.
• The strength of the magnetic lines is the same throughout and is proportional to how close are the lines.
