Fleming's right hand rule
Fleming's right hand rule helps find the direction of induced current when a conductor moves in a magnetic field.
Practice This ConceptMain explanation
Teacher explanation
Stretch the thumb, forefinger, and middle finger of the right hand mutually perpendicular to each other. The forefinger points in the direction of magnetic field, the thumb points in the direction of motion of the conductor, and the middle finger shows the direction of induced current. This rule is especially useful in generators and induction-based questions.
Example
If a conductor moves upward in a magnetic field from north to south, the right hand rule gives the direction of the induced current in the conductor.
Simple analogy
Right hand gives induced current.
Common confusion
Students often use the left hand here or mix the directions of motion and current.
Exam tip
Right hand is for induced current; left hand is for force in motor questions.
