I'm making a circuit involving a electromagnet and I want it to be controlled by an arduino, I want this magnet to be as strong as possible so I need high currents, I did some research and found out that mosfets can handle high currents but I can't figure out how to make them work, can anyone explain how I would achieve the required circuit or link me to anything that might help
