# Which direction is shown in left hand thumb rule?

## Which direction is shown in left hand thumb rule?

If you point your thumb in the direction of the current, as shown, and let your fingers assume a curved position, the magnetic field circling around those wires flows in the direction in which your four fingers point. The Left Hand Rule shows what happens when an electrical current enters a magnetic field.

## How do you use the left hand thumb rule?

“Hold out your left hand with the forefinger, second finger and thumb perpendicular to each other. If the forefinger represents the direction of the field and the second finger represents that of the current, then the thumb gives the direction of the force.”

What does the thumb represent in the left hand rule?

The Thumb represents the direction of Thrust on the conductor (force on the conductor). The Fore finger represents the direction of the magnetic Field. The Center finger (middle finger) the direction of the Current.

### What is Maxwell’s right hand thumb rule?

The Maxwell’s right hand thumb rule states that ‘When the conductor is held in your right hand, such that the direction of the thumb points the direction of the current and the curled finger gives the direction of the magnetic finger. Thus, the direction of the magnetic field and current are mutually perpendicular.

### Who gives right hand thumb rule?

In mathematics and physics, the right-hand rule is a common mnemonic for understanding notation conventions for vectors in 3 dimensions. It was invented for use in electromagnetism by British physicist John Ambrose Fleming in the late 19th century. Right-hand rule.

What is the purpose of right hand thumb rule?

The right hand thumb rule is used to find the direction of magnetic field around a current carrying a straight conductor.

## What are the rules for right and left hand?

Right and Left Hand Rules. If you point your thumb in the direction of the current, as shown, and let your fingers assume a curved position, the magnetic field circling around those wires flows in the direction in which your four fingers point. The Left Hand Rule shows what happens when charged particles (such as electrons in a current)…

## What is the left hand rule in electromagnetism?

left-hand rule. [′left ¦hand ‚rül] (electromagnetism) For a current-carrying wire, the rule that if the fingers of the left hand are placed around the wire so that the thumb points in the direction of electron flow, the fingers will be pointing in the direction of the magnetic field produced by the wire.

How are the fingers of the left hand supposed to point?

For a current-carrying wire, the rule that if the fingers of the left hand are placed around the wire so that the thumb points in the direction of electron flow, the fingers will be pointing in the direction of the magnetic field produced by the wire.

### How are Fleming’s left and right hand thumb rules determined?

This relation is directionally determined by Fleming’s Left Hand rule and Fleming’s Right Hand rule respectively. Directionally means these rules do not show the magnitude but show the direction of any of the three parameters (magnetic field, current, force) if the direction of other two are known.
