What does Fleming's right hand rule give Mcq?
2 Answers
Fleming's Right-Hand Rule is a principle used to determine the direction of motion in an electric motor or generator. It's typically employed in electromagnetism to figure out the direction of force, magnetic field, and current.
Here’s a breakdown of how it works:
1. **Fleming's Right-Hand Rule** states that if you align your right hand so that:
- Your **thumb** points in the direction of the motion (or the force, in the case of a generator).
- Your **index finger** points in the direction of the magnetic field (from north to south).
- Your **middle finger** points in the direction of the current (or induced current in a generator).
Using this rule, you can determine the direction of one of the three variables (force, field, or current) if you know the other two.
### Multiple Choice Question (MCQ) Example:
**Question:**
Fleming's Right-Hand Rule is used to determine which of the following?
A) The direction of the magnetic field in a solenoid.
B) The direction of current flow in a circuit.
C) The direction of force on a current-carrying conductor in a magnetic field.
D) The direction of induced emf in a coil moving through a magnetic field.
**Answer:**
C) The direction of force on a current-carrying conductor in a magnetic field.
### Explanation:
Fleming's Right-Hand Rule helps to determine the direction of force experienced by a conductor when it carries current in a magnetic field, which is critical in understanding the operation of devices like electric generators and motors.

Fleming's Right Hand Rule is used to determine the direction of force experienced by a current-carrying conductor in a magnetic field. It states that if you align your right hand with the thumb pointing in the direction of the magnetic field, and your fingers in the direction of the current, then your palm will face the direction of the force. This rule is crucial for understanding the operation of electric motors and generators.
