5K20.10 Eddy Current Plates
Braking effect of induced eddy current
The motion of a solid metal plate moving in and out between the poles of a strong magnet is damped out by eddy currents. When the slotted edge of the plate is used, the braking effect of induced eddy current is greatly reduced.
-  Strong magnet
-  Aluminum plate
-  Copper plate
- Slide the solid edge of the aluminum plate in and out between the poles of the magnet.
- Slide the slotted edge of the aluminum plate in and out between the poles of the magnet.
- Repeat step 1 to 2 using the copper plate.
- PIRA 5K20.10
- Don't attempt this at home!
