Ring Launcher without Accessories

Product Code: EM-8661

Description

In this classic demonstration of electromagnetic induction, an aluminum ring is propelled straight up to a maximum distance of 2 meters. The changing magnetic field from the AC powered coil causes a changing magnetic flux through the aluminum ring. The induced EMF in the ring sets up a current, which produces a magnetic field. The induced magnetic field opposes the field of the coil, pushing the ring up.

The PASCO Ring Launcher has been optimized to launch the ring higher and to maximize safety by enclosing all wiring inside the case. A thermal shut-off switch protects the coil by preventing overheating when the momentary launch switch is held down for a prolonged time. A red light indicates when the thermal switch is activated, and further launches are prohibited until the device cools.

Voltage: 120 VAC, 60 Hz, not available for 220 VAC
