Question

Why Electric field lines can never intersect to each other?​

Answer 1

because , at the point of intersection, they have to move in the opposite direction which is not possible because they emerge from north pole and merge at South pole.

Answer 2

Magnetic field lines never intersect each other because at the point of intersection there will be two direction which is impossible .

Means in simple language the compass can't show two direction at the same time that's why magnetic field lines never intersect each other.
