Question

If you are given some iron filings and a magnet, describe how you would find the poles of the magnet.

Answer 1

1. Spread the iron fillings on a sheet of white paper and wrap the magnet in the polythene sheet.
2. Run this magnet through the iron fillings.
Now you will see that most of the iron filings stick to two portions of the magnet.
These two portions of the magnet where most of the iron filings stick are the poles of the magnet.
