Illustrate diagrammatically the magnetic field lines of a horse shoe magnet.

Write characteristics of magnetic field lines.

The figure shows the magnetic field lines of a magnetic field. There are three points $A$, $B$ and $C$ in this field. Choose the correct option regarding field strength.

Observe the diagram.

The magnetic poles represented by P and Q respectively are

Name the poles P,Q,R and S of the magnets in the following figures 'a' and 'b'.

"Magnetic field is a physical quantity that has both direction and magnitude." How can this statement be proved with the help of magnetic field lines of a bar magnet?

A bar magnet is used to pick up an iron nail

At which part P, Q, and R is the easiest for the magnet to pick up the iron nail?
