This situation got me confused, this is not a physical setup just a thought.There is a loop of wire , I have that wire on a rotor that I can rotate, I now start to rotate the wire and at the same time attach a current source to the loop like a small battery, current now flows through the wire creating a magnetic field around it ,at the same time I also continue to rotate the wire , assuming the wire is at the " correct" angles to the magnetic field , could I continue to generate current further If I disconnect the battery but keep the wire rotating ?This puzzles me , because if I use a permanent magnet close to the wire and then rotate the wire with hand I get induced current , but can the current in the wire continue to make current from it's own magnetic field if there is energy supplied for the wire to rotate in that field?
