Has anyone ever used a Electromagnet from McMaster? We were going to, and then I noticed that you need a power supply to go along with it, however the power supply is used to convert AC to DC and of course we run DC.
I was originally planning on using a Spike to control a 5698K311 which is a 12 v 8 watt Electromagnet with a 100lbs pull force.
