Abstract:

This activity demonstrates what a dipole magnetic field looks like in 3D. It was developed because the commonly used classroom demo (iron filings on a sheet of paper on top of a bar magnet) leads to student misconception that magnetic fields are two-dimensional. The reverse side of the litho features an artist-s conception of a gamma-ray image of a supernova.
