mmf is which sets up or tends to set up the magnetic flux in magnetic circuit

Note. The term is magnetomotive force, notmagnetic motive force. For a coil, the magnetomotive force is the product of the current flowing in that coil and the number of turns, and is measured in amperes (A), although it is often spoken as 'ampere turns', to avoid any confusion with current.

Magnetic motive force, also known as magnetomotive force (MMF), is a measure of the magnetic field intensity produced by a magnetic source, such as a coil or a magnet. It is analogous to electromotive force in electrical circuits and is used to quantify the strength of the magnetic field created within a material. MMF is calculated as the product of the magnetic field strength and the length of the magnetic path.

What is the unit for Magneto motive Force?

The unit for magneto motive force (MMF) is ampere-turns. It is a measure of the total magnetic field strength produced by a current flowing through a coil of wire.


What is the difference between emf and 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 does lamination affect the magneto-motive force across the air gap of a magnetic circuit?

Lamination reduces eddy current losses in the core material, allowing for a more efficient transfer of magnetic flux across the air gap. This results in an increase in the magneto-motive force across the air gap due to the reduced energy losses in the magnetic circuit.

What is the relationship between a magentic force and a magnetic field?

A magnetic force is the exertion of a force on a magnetic object due to the presence of a magnetic field. The strength and direction of the magnetic force depend on the strength and orientation of the magnetic field. In essence, a magnetic field produces the magnetic force that acts on magnetic objects within its influence.


What is the relationship between magnetic force and magnetic field?

Magnetic force is the force experienced by a magnetic object when placed in a magnetic field. The strength and direction of the force depend on the characteristics of the object and the field. The magnetic field is the region around a magnetic object or current-carrying conductor where another magnetic object experiences a magnetic force.


What force creates a magnetic force?

Typically, an electric current creates a magnetic force. Also, magnetic domains aligned correctly and properly can cause a magnetic force.


Is magnetic force?

Magnetic force is the force exerted between magnetic poles, producing magnetization of force, either of attraction or of repulsion.


What type of force is magnetic force?

Magnetic force is a non-contact force that acts on magnetic materials or moving charges. It is a fundamental force of nature that can attract or repel objects based on their magnetic properties.


What is a force that affects only objects with magnetic domains?

The force that affects only objects with magnetic domains is the magnetic force. This force arises from the interactions between the magnetic fields of objects with magnetic domains and can attract or repel objects with magnetic properties.
