Interesting things:
A direct current motor (DC) motor works on the principle that when a conductor carrying current is in a magnetic field, it produces a torque and will move. A power source is connected to the conductor with the positive side facing the south pole of the magnet and the negative side facing the north pole .

Using Fleming's left-hand rule, we determine the movement of the conductor (clockwise in these images).

Fleming's left-hand rule is a visual mnemonic that makes it easier to remember the direction of current flow. The index finger shows the direction of the field, middle finger current and thumb the direction of the force.

I think I can learn how the magnet interacts with the conductor.
