## What is the application of right hand thumb rule?

Right hand thumb rule is used in determining the direction of torque, Angular velocity, Angular acceleration. Fleming left hand rule is used to find the direction of the motion of conductor in a D. C. motor. Fleming right hand rule is used to find the direction of the induced current in a A. C. generator.

## What is the application of Fleming’s left hand rule?

Fleming’s Left-Hand Rule is a simple and accurate way to find the direction of force/motion of the conductor in an electric motor when the magnetic field direction and the current direction are known. It was originally developed by John Ambrose Fleming, an English electrical engineer, in the late 19th century.

## How do you remember Fleming’s left hand rule?

How to remember Fleming’s left hand rule? Method 1: Relate the thumb with thrust, fore finger with field and center-finger with current as explained below. The Thumb represents the direction of Thrust on the conductor (force on the conductor). The Fore finger represents the direction of the magnetic Field.

## What is the left hand rule in physics?

: a rule in electricity: if the thumb and first two fingers of the left hand are arranged at right angles to each other on a conductor and the hand oriented so that the first finger points in the direction of the magnetic field and the middle finger in the direction of the electric current then the thumb will point in …

## What is L in magnetic field?

L is the length of conductor in the magnetic field measured in metres (m) B = F/IL This defines flux density, B. We can measure F using the current balance. If the current cuts across the magnetic field at the angle θ then the component the current across the field is ISineθ and therefore – F = B I L sinθ

## How does Earth’s magnetic field protect us?

The magnetic field of the Earth plays a very important role in our lives, it protects us from the solar winds. These are currents of particles charged of energy emanated from the sun which emit radiation. The magnetosphere deflects the dangerous ultraviolet rays of the sun, keeping us safe from any risk.
