Question

draw a magnetic lines force in bar magnet​

Answer 1

The properties of magnetic lines of forces are: 1) The direction of magnetic field lines outside the magnet sis from North Pole to South Pole. 2) The direction of magnetic field lines inside the magnet is from south pole to the north pole. 3) No two magnetic field lines intersect each other.

Answer 2

Place the bar magnet in the middle of the paper. Trace the outline of the magnet – that way you can put it back in the exact same spot if it gets bumped. Place the compass at one pole of the magnet and make a dot next to it showing the direction the compass arrow points.
