the longest in the cylindrical-magnet series for visible field-line spread along the magnet axis

demonstrating how a crane lifts loads through the mechanical advantage of a large wheel turning a small axle

this classroom Van de Graaff kit demonstrates charge conservation

letting students sweep through resonance and watch amplitude peak when drive matches natural pitch
