Fleming’s Left Hand Rule – Force on a Current Carrying Conductor in a Magnetic Field
Have you ever wondered how an electric motor works or how electricity can make something move? It all comes down to a special principle in science known as Fleming’s Left-Hand Rule. This is a key part of Class 10 Science and helps explain how electricity and magnetism work together to create motion.
When an electric current passes through a conductor (like a wire) placed in a magnetic field, a force is produced. This force makes the conductor move. To figure out which way it moves, we use Fleming’s Left-Hand Rule.
How Does Fleming’s Left-Hand Rule Work?
Stretch the thumb, forefinger, and middle finger of your left hand so that they are all at right angles to each other:
-
Forefinger points in the direction of the magnetic field (from North to South),
-
Middle finger shows the direction of the current (from positive to negative),
-
Thumb then points in the direction of the motion or force on the conductor.
This simple rule helps us understand the working of electric motors, where electric energy is converted into mechanical energy.
Real-Life Use:
Electric fans, mixers, and electric vehicles all work using this principle. When current flows through coils placed in a magnetic field, the motor spins because of this force.
Learn Fleming’s Left-Hand Rule Easily with Dencity
Understanding science becomes much easier when you can see it in action. The Dencity app offers a virtual science lab where students can perform this experiment safely and interactively.
In Dencity, you can:
-
See how the conductor moves when the direction of current or magnetic field is changed.
-
Use visual arrows to represent magnetic field, current, and force.
-
Pause, repeat, and experiment multiple times to fully understand the concept.
This is perfect for Class 10 Science students and helps them build strong understanding for exams and real-world applications.
