Difference Between Electromotive Force and Magnetomotive Force

In comparing to an electric circuit, the magnetomotive strength is similar the electromotive force. The EMF is the force responsible for the flow of electrons in an electric circuit whereas MMF is the force responsible for driving the magnetic flux or magnetic field lines.


What is Electromotive Force?

Electromotive force, also called EMF, is the driving force behind movement of electrons in an electrical excursion. Electrical charges generate a field around them, and these force fields repel and attract other electrically charged particles. When enough of these charged particles are separated, it creates a potential difference. This deviation in potential that gives rise to electric current is called electromotive forcefulness. It is the terminal potential divergence when no current flows. Information technology is measured in volts and the symbol commonly used for EMF is “East.”

EMF is a blazon of energy per unit of electric charge that is converted reversibly from chemic, mechanical or other forms of energy into electrical energy. One of the most commonly used forms of electricity generation is the electrochemical reaction or better known as a battery. EMF maintains potential difference within an active prison cell. A generator or bombardment converts energy from one course to another. EMF is the cause and voltage is the consequence.


What is Magnetomotive Force?

Magnetomotive forcefulness, or MMF, is analogous to the electromotive force and is defined as the driving force behind the creation of magnetic flux in a magnetic circuit. It is the strength responsible for establishing and maintaining the magnetic field in the magnetic circuit. Information technology may be considered the factor that sets upward the flux. It refers to the magnetic force per unit area that sets up the magnetic flux within and around an object. It can exist created by a permanent magnet or past an electric current flowing in the electric circuit of a scroll.

Similar to how EMF is the driving strength behind current flowing in an electrical excursion, MMF is the driving force behind the magnetic force in a magnetic circuit. The MMF is the forcefulness adult by one ampere flowing through one turn of the curl. The SI unit of measurement for the measurement of MMF is ampere-turn (AT). The MMF is also known as the magnetic potential. It refers to the property of a material to requite to rise to the magnetic field.

Difference between Electromotive Force and Magnetomotive Force

Definition

– EMF is a type of free energy per unit of measurement of electric charge that is converted reversibly from chemical, mechanical or other forms of energy into electrical energy. It is the driving forcefulness behind movement of electrons in an electric circuit. MMF, on the other hand, is the force responsible for establishing and maintaining the magnetic field in the magnetic circuit. It is the magnetic pressure that sets upwards the magnetic flux within and around an object.

Measurement

– EMF is the terminal potential difference when no current flows. It is measured in “volts” and the symbol unremarkably used for EMF is “East.” The MMF is also known as the magnetic potential. The MMF is the force adult past one ampere flowing through ane turn of the curlicue. The SI unit of measurement for the measurement of MMF is ampere-turn (AT).

Formula

– EMF is the energy supplied by a cell or a battery per coulomb (Q) of charge passing through information technology. The magnitude of EMF is the potential difference across the prison cell terminals where there is no current flow. The mathematical expression is E = W/Q, where E is the electromotive force, W is the work done, and Q is the charge.

The magnetomotive force (MMF) of a coil is proportional to the product of the number of turns (North) and the current (I). The formula for MMF is expressed as, Fthou
= IN, where Fm
is the MMF in ampere-turns, I is the current and N is the number of turns.

Summary

In a nutshell, EMF is the driving force backside motility of electrons in an electrical excursion. Similarly, MMF is the driving force behind the creation of magnetic flux in a magnetic circuit. EMF is the final potential difference when no current flows. It is responsible for producing an electrical current in a particular direction. MMF can be created by a permanent magnet or by an electrical current flowing in the electric circuit of a curlicue.

What are MMF and reluctance?

MMF is the driving force backside generation of magnetic fluxes passing through a surface. Reluctance is a concept used in the assay of magnetic circuits.

What is meant by magnetomotive forcefulness?

Magnetomotive force is analogous to the electromotive force and is defined as the driving force backside the creation of magnetic flux in a magnetic circuit. It may be considered the factor that sets up the flux.

How is Magnetising strength related to MMF?

The magnetising force (symbol H) is the drib in magnetic force per meter length of a magnetic circuit having consistent reluctance or opposition to the flow of flux.
