emf is electro motive force i.e force responsible for motion of electrons in any perticular direction in closed circuits. Mmf is magneto motive force i.e force responsible for genration and motion of flux. Rmf is rotating magnatic field.

EMF stands for electro motive force,its the driving force required for the movement of electrons in an electrical circuit. MMF stands for magneto motive force,it is the driving force required to drive the magnetic flux through a magnetic circuit. A rotating magnetic field is a magnetic field that has moving polarities in which its opposite poles rotate about a central point or axis. ... Rotating magnetic fields are often utilized for electromechanical applications such as induction motors and electric generators.

The term emf is used for voltage generated by a source e.g. generator, battery or a photo cell. The term mmf is used in case of magnetic circuits. The term mmf in magnetic circuits is analogous to emf in electric circuits.

EMF = electro motive force MMF = magneto motive force

ईएमएफ शब्द स्त्रोत द्वारे व्युत्पन्न झालेल्या व्होल्टेजसाठी वापरला जातो उदा. जनरेटर, बॅटरी किंवा फोटो सेल. चुंबकीय सर्किट्सच्या बाबतीत एमएमएफआयएस शब्द वापरला जातो. चुंबकीय सर्किटमध्ये एमएमएफचा शब्द विद्युतीय सर्किटमध्ये इएमएफसारखाच असतो. ईएमएफ इलेक्ट्रिक सर्किटमध्ये तयार होतो ज्यामध्ये कॉइलच्या स्वरूपात वाहक असतात.

Electro motive force and mangati motive force

by emf you can produce magnetic feild and by mmf you can produce electricity
