Fleming's Left-Hand Rule - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

Fleming's Left-Hand Rule is a visual mnemonic used by students in GCSE Physics to predict the direction of force experienced by a current-carrying conductor in a magnetic field, such as in electric motors.

By arranging the thumb, forefinger, and middle finger of the left hand perpendicular to each other, this rule helps students remember that the Thumb represents the direction of the Thrust or force, the Forefinger indicates the direction of the Magnetic Field (from North to South), and the Middle finger shows the direction of the Current (from positive to negative).

Fleming's Left-Hand Rule can be used to determine directions of the force, magnetic field and current

This rule is crucial in understanding how electricity can be transformed into mechanical energy in devices like motors.
