the current in the left hand part of the coil causes a downward force, and current in the right hand part of the coil causes an upward force the coil rotates anti-clockwise because of the forces ...

Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...
