Make list of magnetic field lines

Magnetic field is a quantity that has both direction and magnitude. The direction of the magnetic field is taken to be the direction in which a north pole of the compass needle moves inside it.  Therefore it is taken

      by convention that the field lines emerge from north pole and merge at the south pole. Inside the magnet, the direction of field lines is from its south pole to its north pole. Thus the magnetic field lines are closed curves.

Properties of Magnetic Field Lines:

1. 1. A magnetic field line is directed from the North Pole to the South Pole outside the magnet.
   2. A magnetic field line is a closed and continuous curve.
   3. The magnetic field lines are closer where the magnetic field is strong and farther apart where the magnetic field is weak.
   4. The magnetic field lines never intersect each other.
   5. Parallel and equidistant field lines represent a uniform magnetic field.
