Question

Explain Fleming's left and right hand rule. ​

Answer 1

Flemings left hand rule,

According to this rule stretch the forefinger, middle finger and thumb finger such that they are mutually perpendicular, now the first finger indicates the magnetic field, the middle finger(centre finger) Indicates current then the thumb will indicate motion or force

Answer 2

Fleming's left hand rule :

The forefinger, the middle finger and the thumb of the left hand are stretched in mutually perpendicular directions. If the forefinger points in the direction of the magnetic field, the middle finger in the direction of current, then the thumb points in the direction of the force on the conductor.

Fleming's right hand rule :

The forefinger, the middle finger and the thumb of the right hand are held in three mutually perpendicular directions. If the forefinger points along the direction of the magnetic field and the thumb along the direction of motion of the magnetic field and the thumb along the direction of motion of the conductor, then the middle finger points in the direction of induced current.
