To help you answer that question, I'd need a figure that shows what kind of motor (or magnet) it is, the direction of the external magnetic field, whether the field is changing, and which direction the motor is turning.

You have provided none of this information.

it's an electric motor. the current flow is flowing north. the motor is turning clockwise.
the north magnet is actaully on the LEFT and the south magnet is on the RIGHT. There is a circle with a dot in it representing the magnetic force coming out of the page, and there is a circle with a X indicating magnetic force going into the page. These are located on opposite sides of the split ring commutator.
