    You can use iron filings and show how they align to the magnetic field. This can help them visualize the field and make it easier to explain how it works when you explain it.

    It would be best to put the filings on a glass plate or sheet of paper with the magnet underneath. This way you can easily remove the magnet and put the filings back in a container.

    Or you can purchase this 2D Magnetic Field Demonstrator.
