Write any three properties of magnetic field lines.

Explanation

(a) Electric lines of force never intersect with each other. (b) Electric lines of force exert lateral stress on one another. (c) Electric lines of force do not enter a conductor. (d) The direction of electric field is given by the direction of tangent drawn at that point on an electric line of force. (e) In the case of uniform electric field, the electric lines of force remain parallel with each other. (f) Electric flux per unit surface area normal to the flux determines the electric field intensity.
