Ring Launcher
Ring launcher demonstrates Lenz’s law and effects of electromagnetically induced currents in a unique setup.
An iron core is placed in a solenoid. The ring fits over the coil at some height. When we press launch button on control panel to energize the coil, a large magnetic induction builds-up on the axis of coil, generating oppositely directed induced current in the ring. The two oppositely directed inductions repel, aluminum ring shoots up to several feet in air. No effect is seen when using aluminum slit or acrylic ring.
Experiments:
- To demonstrate the Lenz’s law and effects of electromagnetically induced currents.
