What is Fleming's left-hand rule Class 10?
2 Answers
Fleming's Left-Hand Rule is a mnemonic used in physics to help understand the direction of force experienced by a current-carrying conductor in a magnetic field. It is particularly relevant in the study of electromagnetism and electric motors.
### The Rule:
To apply Fleming's Left-Hand Rule, you hold your left hand in a specific orientation:
- **Thumb**: Represents the direction of the **force** (or motion) on the conductor.
- **First Finger**: Represents the direction of the **magnetic field** (from North to South).
- **Second Finger**: Represents the direction of the **current** (from positive to negative).
### How to Use It:
1. Extend your left hand.
2. Position your thumb, first finger, and second finger so that they are mutually perpendicular (like an "L" shape).
3. Align your first finger with the direction of the magnetic field.
4. Point your second finger in the direction of the current.
5. Your thumb will then point in the direction of the force acting on the conductor.
### Applications:
Fleming's Left-Hand Rule is commonly used in:
- Electric motors, where electrical energy is converted into mechanical energy.
- Understanding how electric current interacts with magnetic fields.
This rule helps students visualize and predict the motion of conductors in electromagnetic fields effectively.

Fleming's Left-Hand Rule is used to determine the direction of force experienced by a current-carrying conductor in a magnetic field. According to the rule, if you align your left hand with the thumb, forefinger, and middle finger perpendicular to each other:
- **Forefinger** points in the direction of the magnetic field (from North to South).
- **Middle finger** points in the direction of the current (from positive to negative).
- **Thumb** will then point in the direction of the force exerted on the conductor.
This rule is fundamental in understanding electric motors and generators, where the interaction of magnetic fields and electric currents generates motion.
