Study Notes
Fleming's Left-Hand Rule
- The visual mnemonic associated with electric motors is Fleming's left-hand rule.
- Fleming's left-hand rule was originated by John Ambrose Fleming.
- The purpose of Fleming's left-hand rule is to determine the direction of motion in electric motors.
- When current flows through a conducting wire and an external magnetic field is applied, the conducting wire experiences a mechanical force.
- The direction of the mechanical force experienced by a conducting wire is determined by Fleming's left-hand rule.
- The rule states that the direction of the mechanical force is perpendicular to both the direction of the current and the magnetic field.
- The left-hand is used to represent the three mutually orthogonal axes in Fleming's left-hand rule.
- Fleming's right-hand is used for generators, which is the opposite of Fleming's left-hand rule.
- The mechanical force experienced by a conducting wire is electro-magnetic in nature.
