its my understanding that a generator uses two different poles when it spins in the middle of a copper coil produceing alternating current but this is solved by useing a commutator but i was wondering if u were to put just the north pole of a magnet on the outside of the axle or shaft or whatever so its pointing towards the copper coil and then just attach the south pole end to the axle. would this produce a direct current when spun?

Only magnetic force that breaks thru the coil field will produce electricity. you can take a old electric motor and spin it and it will generate electricity. but if you remove on magnet it will not produce. place the magnet on the out side and it will not produce. it has to make a force between the fields. it is the disruption of this force and the coil fields that produce electricity.

If you could get something like a belt of north poles to run in one direction along a wire you could make direct current, although very weak. Its more efficient to make AC and them pass it through a bridge rectifier or bridge capacitor

no
it will produce direct current if there will be a magnetic field
