Why is it important to use a soft magnetic material as the core of a solenoid?

Soft iron is having very low hysteresis loss. So it would be good to use it as core.

Can INVAR alloy be used as a magnetic core?
Invar can be used as magnetic core material, but there are better choices. Invar is alloyed for its thermal stability. It is iron with a good percentage of nickel. Remember that magnetic core material is usually laminated or is "powdered" in a way to electrically isolate the "bits" of core material so eddy currents will be reduced. A link is posted to the article on Invar put up by our friends at Wikipedia, where knowledge is free.
Why is a iron bar placed in a solenoid?
Solenoids operate by means of electro-magnetic force when a current is passed through them. Iron is easily magnetised and is the only choice for the core.
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.
Is Venus a permanent magnet?
No.-----The earth has an important magnetic field.No, Earth would lose its magnetic field if its molten iron core were not moving. Scientists speculate that Mars had a magnetic field a long time ago but lost it when the planet cooled to the point that its core solidified.
What very important process happens in the outer core why is it important?
the outer core is made mostly of iron, and it is so hot the iron melts. powerful electric currents are formed as the liquid outer core moves. these electric currents create earth's magnetic field. this magnetic field protects the planet from harmful solar radiation and atmosphere.
Which factors affect the magnetic strength of a solenoid which is carrying an electric current?
Factors affecting the magnetic field strength of a solenoid are: - length of the solenoid - diameter of the solenoid - current through the coil around the solenoid - number of turns of the coil of current around the solenoid, usually turns of wire - material in the core
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.
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
How an unmagnetized metal core is magnetized when it is inserted in a solenoid to make an electromagnet?
The solenoid will create a magnetic field inside the solenoid, running parallel to the length of the solenoid. This will happen with or without any metal core, when the current is running. If there is an iron metal core the solenoid's magnetic field will rotate the atoms in the iron in such a way as to reinforce the solenoid's field. The iron atoms are themselves tiny magnets oriented randomly. When alligned, the tiny magnets add to the original solenoid field to give a much stronger magnet.
What is the highest abundant magnetic material on earth?
The Iron at the Earth's core is magnetic and is the most abundant, at the earth's crust, Lodestone is the most abundant naturally occurring magnetic material.
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 steel not a suitable material for core of an electromagnet?
steel is note for an elecromagnet because once it turned magnetic it stays magnetic
What is the difference between core type and shell type transformers?
The difference is between how the windings relate to magnetic material around which they are wound. If this magnetic material surrounds the windings then the device is said to be a shell type transformer. If the windings cover the exterior of the magnetic material then the transformer is said to be of the core type. Please see the link.
What causes magnetic pole?
The Earth's magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core.
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.
What is the difference between electromagnet and solenoid?
A solenoid is a coiled wire with an electric current running through it, causing a magnetic field. An electromagnet is almost the same thing except it is much stronger than a solenoid (usually) and, unlike a solenoid, has a soft, iron core.
