Current-Carrying Conductor in a Magnetic Field A current-carrying wire is surrounded by a magnetic field, and when this wire is placed in another magnetic field the two magnetic fields may interact and produce a force on the wire. This is called the motor effect. A...

The coil is connected to a split-ring commutator When current flows through the coil, the force acting on the coil will turn the coil in a clockwise direction until the coil is in the vertical position There is no current flowing in the vertical position, but due to...
