पर्याय
Fleming's left hand rule
Clock rule
Right hand thumb rule
Fleming's right hand rule
उत्तर
The direction of induced current is obtained by Fleming's right hand rule.
Explanation:
According to Fleming's right hand rule, if we stretch the thumb, middle finger and forefinger of our right hand mutually perpendicular to each other such that the forefinger indicates the direction of magnetic field and thumb indicates the direction of motion of conductor, then the middle finger will indicate the direction of induced current.
