Okay so, when a motor spins in an external magnetic field there will be a change in the magnetic flux threading... When this magnetic flux threading is changed there will also be an induced current that is produced but why is this induced current in the opposite direction of the current that is flowing. Could someone please explain to me why the induced current, counter EMF, is in the opposite direction and why this counter EMF is greater than the input voltage?
