Product Details

If you want the ultimate Eddy current experience this is the coupler for you! Or maybe you just want to make a badass copper wizard's staff that can harness pure magnetic power? Either way it’s pretty magical.  

Eddy Coupling let’s you connect infinite Eddy's together so you can experiment with a longer drop distance. Watch as the magnet continually falls through the different densities of copper as it slows down and speeds up past the windows. 

Simply unscrew the caps on Eddy and swap one or both with one of these couplers and you're away!

Specially designed to interlock with the rest of Eddy so that the electromagnetic flux isn't disrupted as the magnet falls through it, connecting the parts as a continuous chain.  

How many will you stack?
