what is the flemings left hand rule
Answers
Explanation:
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.

Answer: A left hand can be held, as shown in the illustration, so as to represent three mutually orthogonal axes on the thumb, forefinger, and middle finger. If we arrange the thumb, the center finger, and the forefinger of the left hand at right angles to each other, then the thumb points towards the direction of the magnetic force, the center finger gives the direction of current and the forefinger points in the direction of a magnetic field.
- According to Faraday’s law of electromagnetic induction, when a moving conductor is placed inside a magnetic field, a current will be induced in it.
- If the conductor is forcefully moved inside the magnetic field, there will be a relationship between the direction of applied force, magnetic field, and the current.
- It is mainly used in the working of electrical motors.
- The main purpose of the rule is to find the direction of motion in an electric motor.
- The electric motor works on the principle of Faraday’s law of electromagnetic induction and the direction of motion in an electric motor is determined by this popular Fleming’s left-hand rule.
