RVFM Eddy Currents Demo Kit

This kit consists of two tubes about 250mm long, one made from copper, one made from plastic and two discs, one of which is a supermagnet and the other is an aluminium disc of a similar size.

When the supermagnet is dropped down the copper tube, it falls much more slowly than might be expected. The other tube and disc combinations do not show this effect, since eddy currents are only produced using the copper tube and the supermagnet.

• Magnet falls slowly in the copper tube
• Eddy currents are only produced using the copper tube and the magnet combination
• Kit contains:
• 2 tubes approx. 250mm long, one copper, one plastic
• 2 discs: a supermagnet and an aluminium disc of similar size
