Fleming's Rule

Missing

Fleming's right hand rule:


This rule is used to find the direction of induced emf or induced current. According to this rule, if the fore finger, middle finger and thumb of our right hand are directed mutually perpendicular to each other on such a way that the thumb points in the direction of conductor/coil, fore finger points in the direction of magnetic field and middle finger points in the direction of induced emf or induced current.

Fleming's Left Hand Rule:


Fleming’s left-hand rule is used to determine the direction of magnetic force. When we stretch our first three fingers mutually perpendicular to each other; fore finger indicating magnetic field, middle finger indicating current then thumb finger gives the direction of magnetic force.
