An electromagnet, which uses a copper coil and a rod, is a temporary magnet created by passing an electric current through a coil of wire. The rod, often made of iron, is placed inside the coil to enhance the magnetic field. When electricity flows through the copper coil, it creates a magnetic field, and the iron rod inside concentrates and strengthens this field, making the coil behave like a bar magnet with distinct north and south poles.

I am trying to figure out the effects of having the hand(coil) self pump on my rod. Vs having a whole other kind of coil ( real pussy) around my rod. And seeing what kind of different magnetic ,biomagnetic or bioelectric and quantum effects it goes with...what kind of fields it creates and everything else
