उत्तर
Fleming’s left-hand rule is used to determine the direction of force experienced by a current-carrying straight conductor positioned perpendicular to a magnetic field. According to Fleming’s left-hand rule, if the thumb, forefinger, and middle finger are stretched perpendicular to each other. If the thumb symbolises the direction of force, the forefinger represents the magnetic field, and the middle finger indicates the flow of current.
