RING LAUNCHER
Ring launcher demonstrates the Lenz’s law and effects of electromagnetically induced currents in a unique setup.
An iron core placed in a solenoid. The ring fits over the coil at some height. 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, thus aluminium ring shoots up-to several in air. No effect is seen when using aluminium slit or acrylic ring.
