The Ring Launcher is designed to demonstrate Lenz�s Law and electromagnetically induced currents.
\n
It features a base unit with a vertical solenoid made of thick copper wire and a removable iron core.
\n
The launcher includes three types of rings: an aluminium ring without a split, an aluminium ring with a split, and a plastic ring.
\n
The Ring Launcher illustrates electromagnetic induction and magnetic force.
\n
When an aluminium ring is used, the alternating current in the solenoid induces an alternating current in the ring, generating an opposing magnetic field that propels the ring upward.
