उत्तर
Name: Fleming’s left-hand rule
Concept: It represents Fleming’s left-hand rule used for finding the direction of the magnetic force when a current-carrying conductor is placed in a magnetic field.

According to this rule, the left-hand thumb, index finger, and middle finger are stretched so as to be perpendicular to each other. If the index finger is in the direction of the magnetic field and the middle finger points in the direction of the current, then the direction of the thumb is the direction of the force on the conductor.
