Question

Describe an experiment with the help of diagram to plot the magnetic field pattern due to a bar magnet by using iron filings​

Answer 1

Answer:

The easy experiment to demonstrate magnetic field lines is by the use of iron filings.

Place a bar magnet above a write paper on a table.

Using a compass mark the direction of the needle.

Spray iron filings on the paper and tap slightly.

Iron filings are arranged themselves in the same pattern as we drew.

These are the magnetic field lines.

Properties

Field lines form closed loops

They do not cross each other

Density of field lines reduces with increase in distance from the poles
