Notes on Learning's Right and Left Hand Rules

Learning's Right Hand Rule

• Definition: The Right Hand Rule is a mnemonic used to determine the direction of the induced current in a generator due to electromagnetic induction.

• Usage: Remember that the Right Hand Rule applies specifically to generators.

  • Steps to Apply Right Hand Rule:

  1. Extend your right hand: Position your thumb, index, and middle finger so that they are mutually perpendicular.

  2. Thumb: Represents the direction of the motion of the conductor within the magnetic field (conductor's velocity).

  3. Index Finger: Indicates the direction of the magnetic field (from North to South).

  4. Middle Finger: Will show the direction of the induced current (flow of charge).

• Example of Application: If the conductor moves to the right in a magnetic field pointing into the page, then the induced current will flow upwards (based on the orientation of the fingers).
