Question

In the statement of Fleming's left hand rule, what do the direction of centre finger represents

• A. motion
• B. magnetic field
• C. current
• D. none

Answer 1

The correct option is C current

The direction of the current and that of the magnetic field perpendicular to each other and found that the force is perpendicular to both of them. The three directions can be illustrated through a simple rule, called Flemings left-hand rule. According to this rule, stretch the thumb, forefinger and middle finger of your left hand such that they are mutually perpendicular. If the first finger points in the direction of magnetic field and the second finger in the direction of the current, then the thumb will point in the direction of motion or the force acting on the conductor.
