The direction of the induced Electromotive Force (EMF) in a conductor or coil can be determined using Fleming’s Right-Hand Rule. This rule is based on electromagnetic induction and helps visualize the relationship between magnetic field, motion, and induced current.
Given
Phenomenon: Induced EMF in a coil
Objective: Determine the direction of EMF
Calculation
According to Fleming’s Right-Hand Rule: - Thumb → Direction of conductor motion - First Finger → Direction of magnetic field - Second Finger → Direction of induced EMF (current) This rule applies when a conductor cuts across magnetic lines of force, and an EMF is induced due to electromagnetic induction.
Other options: - Fleming’s Left-Hand Rule is used for motors (not for induced EMF). - Faraday’s Law explains the magnitude and cause of EMF but not its direction. - Steinmetz’s Law is related to core losses, not EMF direction.
Final Answer: Fleming’s right-hand rule
