Fleming's Right-Hand Rule is used to determine the direction of _________.
Induced current
Magnetic field
Force on a conductor
Electric flux
Induced current
Fleming's Right-Hand Rule is a visual mnemonic used in electromagnetic induction to determine the direction of the induced current. It is primarily applied in electrical generators where mechanical energy is converted into electrical energy.

Think of a bicycle dynamo where pedaling (motion) through a magnetic field generates electricity for your headlight (induced current).
Right hand for Generators (G-R: Generator/Right hand).
e=тИТdtd╬жBтАЛтАЛ тАФ Faraday's law of induction
I=ReтАЛ тАФ Induced current formula
According to Faraday's law of electromagnetic induction, when a conductor moves across a magnetic field, an electromotive force is induced. The right-hand rule aligns the thumb with the conductor's motion, the forefinger with the magnetic field, and the middle finger indicates the resulting induced current direction.
Thumb represents the direction of motion (force) of the conductor.
Forefinger represents the direction of the magnetic field.
Middle finger represents the direction of the induced current.
Used mainly in dynamos and generators.
Provides a quick, intuitive way to determine current direction in perpendicular fields.
Only valid when motion, field, and current are mutually perpendicular.
AC generators
DC dynamos
| Feature | Right-Hand Rule | Left-Hand Rule |
|---|---|---|
Primary Use | Direction of induced current | Direction of magnetic force |
Option C (Force on a conductor) is determined using Fleming's Left-Hand Rule for electric motors.
Option B (Magnetic field) is typically mapped using field lines or Ampere's Circuital Law.
A is correct тАФ Fleming's Right-Hand Rule is used to determine the direction of the induced current.
Keep clear distinction: Right Hand = Generator (motion to current), Left Hand = Motor (current to force).
