Yes It is defined as currentmultipliedby the number of turns in the coil. You can also use MMF in just a plane sheet of conducting metal, obviously you just treat the number of turns equal to 1.

What is the reason for the distance limitation with the use of mmf?
MMF can stand for lots of things. What is MMF?
What is mmf?
Full-form Of MMF: MAGNETO MOTIVE FORCEDefinition Of MMF ( Magneto motive Force ): Just as electromotive force ( emf ) is necessary to pass current in electric circuit, magneto motive force ( mmf ) is necessary to establish flux in the magnetic circuit. Magneto motive force is the multiplication of current flowing through the coil and the number of turns of the coil.Unit of magneto motive force ( mmf ) is ampere turn.Thus, it should be understood that the magneto motive force can be increased by increasing the number of turns in the coil or by increasing the current flowing through the coil or by increasing both.CommentThe unit of measurement of magnetomotive force is actually the ampere, although it is frequently spoken as 'ampere turn' to prevent its confusion with electric current.
How is Ohm's Law for Magnetism analogous to voltage EMF?
Magnetomotive force (not 'magneticmotive force') is analogous to electromotive force, in the same way that magnetic flux is analogous to current, and reluctance is analogous to resistance. Mmf, flux, and reluctance also have the same 'Ohm's law' relationship as emf, current, and resistance. It is mmf that sets up the magnetic flux; it is the emf that sets up the current.One point worth noting is that despite mmf being measured in amperes (the product of the current flowing through a coil and the number of turns), it is still analogous to emf, and not current!
What is the amount of MMF generated by a 50-turn electromagnetic coil supplied by 12 VDC at a current of one ampere?
600 amperes.
What is the phase difference between stator mmf and rotor mmf?
The phase diference is proportional to the load
What is the difference between emf and mmf?
emf is electromotive force mmf is magnetic motive force emf drives electon where as mmf drives magnetic field
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is meant by maganetization current?
It is the one which is used to produce flux in transformer and main field flux in motor or generator. Flux is proportional to the current passed through the coil. Flux is inversely proportional to the reluctance of the medium that the flux passes through. Flux is analogous to current. Reluctance is analogous to resistance. MMF is analogous to voltage. so if there is a coil carrying 5A current and 10 turns it produces 5*10 = 50 Ampere Turns MMF . so as the current increases MMF increases. If reluctance of the medium used is high there will be more flux. Let us take a transformer in that in order to produce EMF in the secondary we have to give flux from the primary for that we need a current in the primary that is called Magnetizing current . Any way if we load the transformer , the transformer primary carries (N2 / N1 ) * I2 current in addition to magnetizing current. Apart from these two currents there will be another current which is responsible for core loss in the transformer. Please note that all these three currents are at different phase angles i.e. they are not in same phase. Medium for the flux in the transformer is core. If it is a iron core reluctance is more , to produce same EMF it will take more magnetizing current. If we use CRGO steel as core reluctance is less. For less magnetizing current itself we get flux for the required EMF in secondary.
What happens as a current flows through a parallel circuit?
if the circuit is a series circuit (all loads wired in a single line , one after the other ) then the current will be the same in any part of the circuit . if there are several different paths for the current to take , then each path will carry a different percentage of the total current . when each of these different current values are added together , they will equal the total supplied current.
Is total debt considered the same as total liabilities?
it depends if you include current liablitites in total debt then yes total debt is equal to total liab otherwise not
What does mmf mean in adult personal ads?
MMF mean Man Man Female and MFF mean Man Female Female. its basically the 2 ways to have a 3 sum.
What aspect of a series circuit is the same for each resister as well the total circuit?
current
