Answer 2

Answer:

The correct answer is B. Fleming’s left hand rule.

Explanation:

Electric motors use Fleming's left hand rule.

A current carrying conductor when placed in an external magnetic field experiences force which is perpendicular to  both magnetic field and to the direction of flow of current.

Holding the forefinger, thumb and middle finger perpendicular to each other we can find out the direction of magnetic field, current or thrust or motion.

The middle finger points towards the direction of current, forefinger towards the direction of a magnetic field and thumb towards thrust/motion. When two of these are given we can find the direction of the third.
