Question

(iii) State Fleming's left-hand rule.

Hint:

Remember: Left-hand rule applies for motors (motion), while right-hand rule is used for generators (current generation).

Answer 1

Fleming's left-hand rule is used to determine the direction of force experienced by a current-carrying conductor placed in a magnetic field. The rule states:
\begin{center} If you stretch the thumb, forefinger, and middle finger of your left hand at right angles to each other, then: \end{center} - The thumb points in the direction of the motion (force) of the conductor.
- The forefinger points in the direction of the magnetic field.
- The middle finger points in the direction of the current through the conductor.
This rule helps to determine the direction of motion when a current-carrying conductor is placed in a magnetic field.
