Ring Launcher Model | Manufactured by Samtech Instruments

The Ring Launcher Model is a fascinating demonstration apparatus that explains electromagnetic induction and Lenz’s law in physics. When powered by 220V AC, the energized copper coil generates a magnetic field, launching the aluminum rings along the iron rod. Students can observe how the closed ring jumps higher compared to the open ring, making it a powerful teaching aid.

🔎 What is the Ring Launcher Model?

This model demonstrates how alternating current in a coil induces a current in a nearby conducting ring, producing repulsion due to opposing magnetic fields. It is widely used in physics classrooms and STEM labs to teach electromagnetic induction, eddy currents, and Lenz’s law.
