Magnetic Lines Of Force
Magnetic filed may be defined as the space around a magnet in which the affect of magnet can be experienced. The magnetic field of a magnet is represented by equidistant parallel lines called magnetic lines of force. The magnetic line of force may be defined as the path along which the north pole of compass needle moves.
Properties of Magnetic Lines of Force
Following are the important properties of magnetic lines of force:
1. The magnetic lines of force originate from north pole of a magnet and ends at its south pole.
2. No two magnetic lines of force can intersect each other because if the two magnetic lines of force intersect each other, it would mean that the needle would point towards two directions at the point of intersection, which is not possible.
3. The degree of closeness of magnetic lines of force shows the relative strength of magnetic field.
