Eddy Current Demonstration Apparatus

The Eddy Current Demonstration Apparatus is a physics laboratory apparatus used for demonstrating eddy currents, electromagnetic induction, and magnetic damping effects. Designed for students and educators, it helps explain how changing magnetic fields generate induced currents and produce opposing magnetic forces.

Product Description

The STEMAids Eddy Current Demonstration Apparatus is an educational electromagnetism model designed to demonstrate the practical effects of induced currents in conductive materials. It helps students observe how magnetic fields interact with moving conductors and how this interaction can create resistance to motion.

Eddy currents are circulating currents produced inside a conductor when the magnetic flux through it changes. These induced currents generate magnetic fields that oppose the change causing them, providing a practical demonstration of Lenz’s law and electromagnetic damping. The exact disc material, magnet specifications, dimensions, and included accessories should be confirmed from the latest STEMAids product documentation.
