Question

. If you are provided with iron filings and a bar magnet, state how you can use these to show patterns of the magnetic field?

Answer 1

Answer:

Put two magnets underneath a piece of paper with 1 inch apart.

Carefully and slowly shake some iron filings onto the piece of paper above the magnets.

If the iron filings are too far from the magnets, gently tap or shake the paper to move them closer to above the magnets.
