Question
State and explain Fleming's right hand rule.
Solution
Fleming's right-hand rule states that when thumb, forefinger and centre finger of right hand are held mutually perpendicular to one another, thumb, forefinger and centre finger represent directions of motion, field and current induced in the conductor, respectively.
