3. List the properties of magnetic lines of force.

Ans. Properties of magnetic field lines of force: (i) Magnetic field lines travel from N-pole of magnet towards 5-pole, outside the magnet and from S-pole to N-pole inside the magnet. (ii) The strength of magnet/magnetic field is given by how close the field lines are if the field lines are closer magnet is stronger. (iii) No two magnetic field lin
