What happens if a wire has flowing electricity (circular wrap) and a magnet is brought near?

Question

Basically, if you are conducting the Faraday experiment where you slide a magnet through a coil of wires, but, at the same time, there is already electricity flowing through the wire, then what happens. What would happen to the magnetic field being formed by the electricity flowing the coil, could it possibly spread? If anything does happen, will it continue to happen if the magnet is places in a non moving position or will it only happen in the presence of a moving magnetic field?

Answer 1

There are two magnetic fields playing games with each other. The net magnetism is the sum of what is happening. The coil makes a field that is stronger in the middle. If the magnet moves, it varies the electric current in the wire. If a galvanometer is connected to the coil as in the classic experiment, instead of going to zero when the magnet is still, it will show the coil current and when the magnet is moved, the current will vary up and down from that amount.
