Assertian: Basic difference between an electric line and magnetic line of force is that former is discontinous and the latter is contiuous or endless.
Reason: No electric line of forces exist inside a magnet.

Text Solution

Verified by Experts

The electric lines of force always leave or end on the surface of a charged body.
Magnetic lines of induction are closed curves starting from north pole and ending on the south pole of the magnet.
Within the magnet they run from south to north.
