(b) Draw two field lines around a bar magnet along its length on its two sides and mark the field directions on them by arrow marks.​

Answer 1

there is some force is lie around the magnet is called magnetic field .. by the Fleming left hand rule we can determine the direction of magnetic field.

Bhai second Wala

Answer 2

Answer:

Explanation:

Magnetic field lines of force are the lines drawn in a magnetic field along which a hypothetical north magnetic pole code more if it is free to do so.

The direction of magnetic field at a point is direction of the resultant force acting on a hypothetical North Pole placed at that point. The direction of magnetic field at a point can be found by placing a small magnetic compass at that point the north end of the needle indicates the direction of the field.

B. That figure
