Illustrative Examples
Imagine a manual flashlight powered by hand-cranking. As the internal magnet traverses the flashlight’s coil, Fleming’s Right-Hand Rule provides insights into the generated electric current’s direction. This principal works in a similar manner in various scenarios such as encompassing wind turbines, hydroelectric generators, and bicycle dynamos.
Difference Between Fleming’s Left-Hand and Right-Hand Rule
Aspect | Fleming’s Left-Hand Rule | Fleming’s Right-Hand Rule |
---|---|---|
Purpose | Used to determine the direction of the magnetic field around a current-carrying conductor. | Used to determine the direction of the force on a current-carrying conductor in a magnetic field. |
Input Parameters | Thumb – Represents the direction of the current. Forefinger – Represents the direction of the magnetic field. Middle finger – Represents the direction of the force (if any). | Thumb – Represents the direction of the force (on the conductor). Forefinger – Represents the direction of the magnetic field. Middle finger – Represents the direction of the current (in the conductor). |
Application | Used when you want to find the magnetic field produced by a current. | Used when you want to find the direction of force on a current-carrying conductor in a magnetic field. |
Conductor Orientation | Applied to a single current-carrying conductor. | Applied to a current-carrying conductor in a magnetic field. |
Motion of Conductor | Determines the magnetic field’s direction created by the current. | Determines the direction of the force experienced by the conductor. |
Common Applications | Electrical engineers use it in designing circuits and analyzing current flow in wires. | Used in physics and engineering to determine the direction of forces acting on current-carrying conductors (e.g., electric motors, generators). |
Magnetic Field Direction | Determines the direction of the magnetic field produced by the current. | Determines the direction of the magnetic field that the conductor is placed in. |
Force Direction | Not applicable. It doesn’t determine the force on a conductor. | Determines the direction of the force acting on a current-carrying conductor. |
Fleming’s Left Hand Rule and Fleming’s Right Hand Rule
Fleming’s Left-Hand Rule and Fleming’s Right-Hand Rule are principles employed to ascertain the force’s orientation experienced by a conductor carrying electric current when exposed to a magnetic field. These rules were provided by John Ambrose Fleming and form the basics of electromagnetism. Their primary purpose is to predict the direction of the force acting on a conductor in relation to the magnetic field and the current’s flow.
