How It Is Used
Each school bar magnet is placed under paper with iron filings or surrounded by a plotting compass to map its field lines, and two magnets are used to show attraction and repulsion. The pair can also be used in deflection experiments to compare magnetic moments, then stored with the keepers across the ends and the spacer between the bars.
