Question
Give the characteristics of magnetic field lines.
✓
Answer
→Characteristics of magnetic field lines are as follows :
(i) The magnetic field lines form continuous closed loops. In the region outside a magnet, the magnetic field lines are from N to S , whereas in the region inside the magnet, the field lines are from S to N .
(ii) The tangent to the field line at a given point represents the direction of the magnetic field $(\vec{B})$ at that point.
(iii) The larger the number of field lines crossing per unit area, the stronger is the magnitude of the magnetic field $\overrightarrow{ B }$.
(iv) Two magnetic field lines do not intersect each other. Because if they do, at the point of intersection, the magnetic field would have two directions, which is not possible.
