Question

what is left hand rule and write the rule​

Answer 1

Explanation:

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 the direction of the force on the conductor

Answer 2

Answer:

The Right Hand Rule, illustrated at left, simply shows how a current-carrying wire generates a magnetic field. 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. You need to contort your hand in an unnatural position for this rule, illustrated below. As you can see, if your index finger points in the direction of a magnetic field, and your middle finger, at a 90 degree angle to your index, points in the direction of the current.
