When experimenting with the simulation, you can manipulate the size of the motor, the strength of the input current, the strength of the magnetic field, and the number of turns in the wire:
In the general case the magnitude of the magnetic moment equals the current i times the area S of the loop: The direction of m is determined by the right hand rule; curl the fingers on your right ...In the general case the magnitude of the magnetic moment equals the current i times the area S of the loop: The direction of m is determined by the right hand rule; curl the fingers on your right hand around the loop in the direction of the current and your thumb points in the direction of m. The angular momentum of the loops carries the rotation of the axle through the zero torque region, which occurs when the magnetic moment is either perfectly parallel or perfectly anti-parallel (i.
