उत्तर १
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.
उत्तर २
- Fleming's Left-Hand Rule applies to calculating the force experienced by a current-carrying straight wire in a perpendicular magnetic field.
- According to Fleming's Left-Hand Rule, the thumb indicates force (F), the index finger indicates magnetic field (B), and the middle finger indicates current (I).
- Aligning the three directions according to the rule reveals the direction of the force exerted on the conductor.
- This law applies when the magnetic field, current, and force are perpendicular to one another.
