Fleming's Left-Hand Rule for Electric Motors

Understanding the Basics

Fleming's left-hand rule is a visual mnemonic used to determine the direction of force experienced by a current-carrying wire placed in a magnetic field. It is commonly used in the context of electric motors and generators.

Application in Electric Motors

In an electric motor, a current-carrying wire is placed between the poles of a magnet. Fleming's left-hand rule can be used to show that the force acting on the wire will cause it to rotate. When the current flows in one direction, the force will be in one direction, and when the current is reversed, the force will be in the opposite direction. This alternating force causes the wire to rotate continuously.
