The Concept of Magnetic Field
Magnetic field is a region around a magnet where magnetic influence is experienced or felt. It is also a region where it exerts force on other magnets. It is a vector quantity.
Properties of Magnetic Lines of Force
(i) They originate from the N-pole and end in the S-pole. ii. Two magnetic lines of force do not cross each other.
(ii) Where the lines of force are close together, the intensity of the field is greater; where they are widely separated, the intensity is less and where they are parallel, the intensity is uniform.
