In Fig. draw at least two magnetic field lines between the two magnets.

The magnetic field lines inside a bar magnet

Draw magnetic field lines around a bar magnet.

Draw magnetic field lines around a bar magnet.

Fig. shows a bar magnet placed on the table top with its north pole pointing towards south. The arrow shows the north-south direction. There are no other magnets or magnetic material nearby. Insert two magnetic field lines on either side of the magnet using arrow head to show the direction of each field line.

Which of these materials requires the least value of magnetic field strength to magnetize it ?

Why don't two magnetic field lines intersect each other?

In Fig, find the magnetic field at point P.

State four properties of magnetic field lines.

Two identical magnetic dipoles of magnetic moments 2Am^2 are placed at a separation of 2m with their axes perpendicular to each other in air. The resultant magnetic field at a mid point between the dipole is

State any two properties of magnetic field lines.
