Question

In context with Fleming’s left hand rule which statement is incorrect
(A) Middle finger points to direction of magnetic field
(B) Middle finger points to direction of electric current
(C) Fore finger points to direction of magnetic field
(D) Thumb points to direction of force

Answer 1

Option (A) is incorrect and hence the correct option.

Explanation :-

According to the Flemming's left hand rule, if we stretch our thumb, fore finger and middle finger in such a way that they are mutually perpendicular to each other, or in simple words all the fingers are making 90° angle to each other and if our forefinger is directed towards magnetic field and if our middle finger is pointing in the direction of current then only our thumb will give us the direction of force.

This is the Flemming's left hand rule.
