This all-in-one demonstration system includes the Variable Gap Magnet (EM-8618) and the Magnetic Force Accessory (EM-8642A).
Demonstrate Magnetic Damping
Swing the solid aluminum paddle through the gap and it stops dead, the motion damped due to eddy currents. Now try the slotted paddles. One swings freely, while the other is immediately damped.
Demonstrate Diamagnetism and Paramagnetism
The diamagnetic glass rod (Figure a) aligns transverse to the field; the paramagnetic aluminum rod (Figure b) aligns with the field.
Demonstrate Force on a Current-Carrying Wire
Pass a current through the wire swing (power supply not included) to investigate the right-hand rule for magnetic forces.
