Eddy Current Disc Demonstration Model

The Eddy Current Disc Demonstration Model is a physics laboratory apparatus used for demonstrating eddy currents, electromagnetic induction, and magnetic damping effects. Designed for students and educators, it helps visualize how changing magnetic fields can produce induced currents and opposing forces in conductive materials.

Product Description

The STEMAids Eddy Current Disc Demonstration Model is an educational electromagnetism apparatus developed to support practical learning of Faraday’s law of electromagnetic induction and Lenz’s law. The model allows students to observe the interaction between a magnetic field and a conducting disc through controlled demonstrations.

Eddy currents are circulating electrical currents induced inside a conductor when the magnetic flux through it changes. These currents create magnetic effects that oppose the change producing them, resulting in electromagnetic damping. The apparatus provides a practical method for explaining these concepts in physics laboratories. The exact disc material, magnet specifications, dimensions, and included accessories should be confirmed from the latest STEMAids product documentation.
