This model shows the magnetic field between the magnets and the current flowing through the wire when a battery is connected. It also shows the magnetic relationship between the wire and the magnets. The electric current is supplied by the battery. The current flows from positive to negative.
This model shows the current flowing through the wire when a battery is connected.
This model shows the exploded view of a DC motor. It shows how the electric current flows through the coil and produces a torque that turns the DC motor, which is caused by the magnetic force. It shows the rotational force of the rotating armature, brush, and shaft.
