5K20.65 Electromagnetic Can Crusher

[Setup Time: 15 Min.] [Current Condition: Broken]

Info

A high energy capacitor discharges into a coil around an aluminum can. The eddy current in the can causes it to blow apart. This demo can also be used to show conduction in air, repulsion of opposite currents, and conversion of electrical energy to thermal energy.
