Question

State Fleming's left-hand rule. Name a device based on this rule.

Answer 1

Step 1: Fleming's Left-Hand Rule

Stretch your left hand's thumb and first two fingers perpendicular to one other. The thumb indicates the direction of the force on the conductor if the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current.

Step 2: Device Based on Fleming's Left Hand Rule

Electric Motor

A device that converts electrical energy into mechanical energy is known as an electric motor. When a current-carrying coil is put in a magnetic field, and the current is conducted through it, the coil experiences a force.
Fleming's left-hand rule is used to establish the direction of the force.
