I have an electromagnetic chuck on my surface grinder. 6X12 Electro-Matic with an old tube powered dc rectifier. My question is can I add a device in line to control the power of the magnet? Would a variac control work? If so would it be used on the ac input side or dc output side. Appreciate any help or suggestions. I will add that this is for a hobby application so Im not looking to spend a bunch of $$on a new chuck and or rectifier.
Thanks
