I have a project where I am to build a DC motor with a commutator and brushes out of simple materials, such as scrap wood, magnet copper wire, permanent magnets and a 9V battery. I have already assembled the motor. When I connect the 9V battery, the coils do have a magnetic field as they will attract a paperclip, but the armature won't turn. If I give it a push, they become attracted to the permanent magnets on each side instead of repelling them to keep it turning. Any ideas why?

(might be 1 or 2, MCQ questions were having images given with them, which we couldn't insert, so ignore those questions if you cannot answer, sorry for inconveinience created, i tried to delete them but might be couldn't done all) 3) Single phase induction motors work because: a) The oscillating magnetic field can induce starting torque in a rotor. b) The oscillating magnetic field can induce running torque in a rotor. c) A capacitance or inductance can create the phase...
