i would assume the answer is yes, my understanding - reversing the current flow would change the polarity.google said:Electromagnetism is produced when an electrical current flows through a simple conductor such as a piece of wire or cable. A small magnetic field is created around the conductor with the direction of this magnetic field with regards to its “North” and “South” poles being determined by the direction of the current flowing through the conductor.
I don't see why that would not work.I'm thinking of an application where a machine, when in set up mode, would have two electrical magnets opposing each other, creating a gap (of about 1/8") through which I could thread a substrate.
