No- it would turn 180 deg and stop...once the north and south poles are attracted to each other, without a system to reverse the poles to keep it in a constant repel/attract series (i.e. alternating current) it will simply stop half way around and stay there.
Be blessed :-)

No, permanent magnet motors are DC motors that use direct current to have the other part of the motor interacting with the permanent magnet. So you have coils for the electromagnetic field. A motor has a stator and a rotor. On a permanent magnet motor, either the stator OR the rotor consists of a permanent magnet. The other part is a switchable coil-electromagnet. There is no "free-energy" out of a permanent magnet to make a motor run on its own.

HAHA another perpetual motion machine!
Short answer: No.
Long answer:
No. The permanent magnets on your axle would both repel and attract the permanent magnets on your casing. The two opposing forces would be equal and opposite, so the motor would stay still (not counting all sorts of wierd properties magnets have) OR it would continue rotating once in motion. However another force acts on the motor - friction. This force will slow it down very quickly and stop it. Even if you make it frictionless - the motor moves no load and is suspended in a gravity-less vacuum, the magnets still have influence on each other that would slow and stop the motor. In short each magnetic field induces a new magnetic field in the materials of the casing, axle, and other magnets, which acts in an opposing direction. Too bad, perpetual motion would be way cool.

No. There is no free lunch. You still need to add energy to the system to get work from the motor. If this were the case all of the permanent magnet motors in the world would be spinning away all the time producing free energy.

No. I see what you are getting at but having static magnets inside rotary magnets or vice versa will not cause rotation, just equillibrium.

there is no way to create energy, just transfer it.
I think that was the 2nd day of class?

You are failing Engineering, aren't you?
