Question

State Fleming's left hand rule. Apply this rule to determine the direction of force experienced by a straight current carrying conductor AB placed in a uniform magnetic field as shown.

Answer 1

1. Extend your left hand's forefinger, middle finger, and thumb perpendicularly. The forefinger represents the magnetic field direction, the middle finger represents the current direction, and the thumb indicates the conductor's motion.
2. The displacement of current across a conductor indicates a force acting on it. The Left Hand Rule, a physics principle, explains how a conductor's mobility is influenced by its magnetic field and current direction.
