In Fleming's left hand rule, which physical quantity is represented by the middle finger?
Direction of electric current
The correct answer is option 3 i.e. Direction of electric current.
In Fleming's left-hand rule, the middle finger represents the direction of electric current. This rule is used to find the direction of force acting on a conductor carrying current when placed in a magnetic field. The left hand is positioned such that the thumb points in the direction of the force, the index finger points in the direction of the magnetic field, and the middle finger indicates the direction of electric current. This rule helps in understanding the relationship between current, magnetic field, and force in electromagnetic interactions.
