Which of the following device is governed by Flemming’s Left Hand Rule 

The correct answer is Electric motor.

Key Points

• Fleming's Left Hand Rule is used to determine the direction of force on a current-carrying conductor in a magnetic field, which is essential in the functioning of an electric motor.
• According to the rule, if you align your thumb, forefinger, and middle finger perpendicular to each other, the thumb represents the direction of force (motion), the forefinger the magnetic field, and the middle finger the current.
• Electric motors convert electrical energy into mechanical energy, and Fleming's Left Hand Rule helps in predicting the direction of this mechanical force.
• This principle is critical in various applications, including fans, washing machines, and other household appliances that use electric motors.

Additional Information

• Fleming's Right Hand Rule
  • This rule is used to determine the direction of induced current when a conductor moves in a magnetic field.
  • It is applicable in generators, where mechanical energy is converted into electrical energy.
• Electric Generators
  • Electric generators operate on the principle of electromagnetic induction to convert mechanical energy into electrical energy.
  • They utilize Fleming's Right Hand Rule to determine the direction of induced current.
• Magnetic Field
  • A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
  • It is fundamental to the operation of both motors and generators.
• Electromagnetic Induction
  • It is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field.
  • This principle is used in transformers, induction coils, and various other electrical devices.
