Why does the soft iron core increases the strength of magnetic field?
Wiki User
∙ 11y ago
Iron core (usually soft iron core) is a highly ferromagnetic material. Ferromagnetic materials allows (and attracts) the magnetic field lines to pass through it.
When such a material is used in the electromagnet, the magnetic field lines passing through it increases, thereby, the strength of the electromagnet increases.
So my friend, I hope you are satisfied with the answer.

ANALOGY: Just as sound travels best in dense solids, magnetic fields travel best in [soft] iron
When the magnetic field travels through the soft iron it is amplified/ intensified so that the mutual induction between two coils becomes more efficient

The source of the magnetic field on the Sun is?
the core
How can a scrap heap magnets strength be increased?
There are three different ways to increase your magnet:Increase the voltage or current.Add more turns of the coil.Add a magnetic core inside the coils which will focus the magnetic field.
Earth's magnetic field results from movements in the what?
The Earth's magnetic field results from electric currents in the mantle and outer core around the iron solid core; every electricmagnet is prduced as a result of electricity flowing around a iron core - the same principle works in our own magnetic field.
The dynamo theory states that earths magnetic field is created in layers?
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
Why doesn't the moon have a magnetic field?
Venus does not have a magnetic field because its rotational period is very slow. This means that if its core had a liquid metal component, it would not be moving fast enough to generate a field.
If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped
Why is the core of a moving coil galvanometer made of soft iron?
The term galvanometer is used to refer to a meter which can measure small currents, usually in the mA (10-3A) or mA (10-6A) range. When a soft iron core is used, the magnetic field lines tend to crowd through the core. It is because soft iron core is ferromagnetic in nature. As a result, the strength of the magnetic field due to the field magnet increases, which in turn increases the sensitivity of the galvanometer.
How the magnetic field around a solenoid can be strengthened?
The strength of the magnetic field produced by a current carrying solenoid depends on:The number of turns - larger the number of turns, greater is the magnetism produced.The strength of the current - when current increases, magnetism also increases.Nature of 'core-material' used in making the solenoid - if we use soft-iron as a core for the solenoid, then it produces the strongest magnetism.
How does the section of iron coil influence the magnetic field?
Do you maybe mean an 'iron core?' If so, an iron core strenghthens the magnetic field significantly. *If the coils are wound closer together the fluxlines are more dense and increase the strength of the field slightly (an iron core strengthens the field by allowing the magnetic field to propagate inside it better than air).
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
How does the strength of an electromagnet with an iron core compare to an electromagnet that simply has air at its core?
Permeability of the medium, that too, if it is ferro-magnetic material then it gets increased to a larger extent and so the magnetic induction too increases enormously.
What are sources make up the earths magnetic field?
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
Does the number of turns in the electromagnet effect its strength?
Magnetic induction B = mu * n * I Here mu is the magnetic permeability of the core material. n - the number of turns per unit length and I - the current in ampere. So as number of turns increases the magnetic effect too increases
What creates the Earths magnetic field?
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
Why is iron nail used to make an electromagnet?
because exhibits maximum flux density requires small magnetising field exhibits low hysteresis loop
Does Mercury have a magnetic field?
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core. The strength of the field has been estimated as approximately 1% of Earth's. (see link)
