Class 10

Answer 1

The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. They show the direction and strength of magnetic field. ... The direction of magnetic field is taken to be the direction in which a north pole of compass needle move inside it.

Answer 2

Magnetic Field

The region surrounding a magnet in which the influence of that magnet is felt, is called the magnetic field of that magnet.

Magnetic field lines

• Magnetic field lines in a magnetic field is defined as a continuous line such that the tangent drawn at any point on it gives the direction of magnetic field at that point.

• A magnetic line of force emerges from the north pole of a magnet and terminates at the south pole.
