they dont actually touch, it uses a rotating magnetic field on one side and a wound coil on the other to push the electrons in the coil and create flow. look up Faraday Principle and how it works. same thing.

Yeah I know they don’t touch, but I am kind of surprised they actually use a rotating magnetic field, it seems like old technology. It must be cheap to build.
