Eddy Current Apparatus
Product Code : SCL-PLE-11637
Quick Answer: The Eddy Current Apparatus swings solid and slotted copper or aluminium plates past strong permanent magnets, so students can compare how quickly each is damped and see eddy currents opposing motion, as Lenz’s law predicts.

Key Features
- Solid and slotted conducting plates for comparison.
- High-purity copper or aluminium plates.
- Neodymium or alnico permanent magnets.
- Low-friction bifilar or central pivot suspension.
- Non-magnetic polymer or hardwood base.
Technical Specifications
| Specification | Value |
|---|---|
| Plates | Copper or aluminium, solid and slotted |
| Magnets | Neodymium or alnico permanent magnets |
| Suspension | Bifilar or central pivot |
| Base | Non-magnetic polymer or treated hardwood |
How It Is Used
The solid plate is set swinging through the magnetic field and stops after a few swings, while the slotted plate keeps swinging much longer because the slots break up the eddy current paths. The comparison shows electromagnetic damping and the idea behind magnetic brakes.
Frequently Asked Questions
Why does the Eddy Current Apparatus include a slotted plate?
The slots interrupt the paths of the eddy currents, so the slotted plate is damped much less than the solid one. Comparing the two shows that the braking comes from induced currents.
