What are 4 properties of magnetic field line?

Magnetic field lines are the imaginary lines used to calculate the extent of the strength of a magnetic field.

The magnetic field lines are:

  • Emerging from the north pole of the magnet to its south pole.
  • These lines are curved and continuous.
  • The magnetic field lines are parallel to each other i.e they never intersect each other.
  • The number of magnetic field line per unit area or magnetic flux is more at the poles, that is the reason why the magnetic field strength is more at poles.
