in which thing fleming's left hand rule employed?
There are several 'rules' used with d.c. motors. Perhaps you are thinking of Fleming's Left-Hand Rule (for conventional flow) or Fleming's Right-Hand Rule (for electron flow)? These rules were devised by the British academic, Sir Ambrose Fleming, to help his students remember the relationship between the directions of current, magnetic field, and force.
You may be thinking of Fleming's Left-Hand Rule (for conventional current flow) or Fleming's Right-Hand Rule (for electron flow), devised by academic Sir Ambrose Fleming, as a aid for determining the direction of the resulting force acting on a current-carrying conductor within a magnetic field, when the direction of current and the direction of the magnetic field are known.
Who first suggested Fleming's left hand rule?
Fleming's right hand rule.

The left-hand rule, a rule used in physics to determine the direction of magnetic force in a conductor, was developed in the 19th century by scientists such as John Fleming and Oliver Heaviside. However, the specific date of its invention is not precisely recorded.
John Hand was born in 1902.
John Hand Building was created in 1912.

To use your left hand to determine the direction of the voltage developed in moving conductor place your forefinger in the direction of the lines of force. Fleming developed this hand rule.
