Question

Define magnetc field. Describe the activity to draw magnetic

Answer 1

magnetic field is the space around a magnet wherein magnetic force can be felt.

The magnetic field lines of a bar magnet can be mapped using a magnetic compass . the compass can be moved from one pole of the bar magnet to the another pole. we can trace the field lines by moving the compass gradually and drawing a corresponding line which the compass would trace while following a particular line of force

in this activity we will get a magnetic field around the magnet

Answer 2

Answer:

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.The region around a magnet in which the force of attraction or repulsion produced by the magnet can be detected is magnetic field.

Explanation:

Activity to draw a magnetic field line outside a bar magnet from one pole to another pole: Take a small compass and a bar magnet. Place the magnet on a sheet of white paper fixed on a drawing board, using some adhesive material. Mark the boundary of the magnet. Place the compass near the north pole of the magnet.

The magnetic field lines are the lines draw in a magnetic field along which a north magnetic pole would move. The magnetic lines are also known as magnetic lines of force.

Activity to draw a magnetic field line outside a bar magnet from one pole to another pole.

Take the magnet on a sheet of white paper fixed on a drawing board, using some adhesive material.

Mark the boundary of the magnet.

Place the compass near the pole of the magnet. The south pole of the needle points toward the north pole of the magnet. The north pole of the compass is directed away from the north pole of the magnet.

Mark the position of two ends of the needle.

Now move the needle to a new position such that its south that its south pole occupies the position previously occupied by its north pole.

In this way, proceed step by step till you reach the south pole of the magnet.

Join the point marked on the paper by a smooth curve. This curve represents a magnetic field line.
