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.

What is a example of converting electrical energy into magnetic energy?
An electromagnet, a coil of wire round a magnetic core. An electric current in the wire produces a magnetic field round the core, which contains energy which could be used to lift a load.
Why invar steel is used in making pendulum?
Invar has very low co-efficient of thermal expansion. Hence there will be only very little change in expansion when the temperature varies. As a result of which the pendulum does not change its duration of oscillation which is very important for time to be apt. Gmk
What is supermalloy?
Supermalloy is a metal alloy that is 79% nickel, 5% molybdenum and 16% iron. It is used in mechanical and electronic components like hard drives. It is disigned to have a very high magnetic permeability and a low coercivity, meaning that magnetic fields can flow though it very easily. It is also a soft magnetic material, meaning that it doesn't stay magnetized itself once the magnetic field is removed.
What material is used in electro magnets?
The magnetic field in an electromagnet is actually produced by the coil of wires with a current running through it. However certain materials, termed 'ferromagnetic' materials concentrate the magnetic flux when a rod of the material is placed within the coil (termed the 'magnetic core'). The most common of materials used for this have been iron based.
What is the main element used to make alloy wheels?
metallic element used as an alloy in wheels for classic cars
Why is invar so often used to make acurate thecnical instrements that are used in hot situations?
invar steel is an alloy of steel and nickel . it doesnt expand like any other material at high temperatures .therefore it is used to measure accurately
What are the applications of linear expansion?
Invar (a special iron - nickel alloy) is used in pendulam instead of aluminium ,in order to decrease the expansivity.
Does invar is used in missiles?
There are invar missiles.
What is inver metal?
An inver alloy has been known as a material having a small coefficient of linear thermal expansion. For example, a Fe64Co36 alloy, a Fe66Co34 alloy and a Fe73Co27 alloy are well known as the inver alloys. By employing the inver alloy as a magnetic pole of the recording head, the projection length of the magnetic pole can be reduce to one-tenth of the projection length of the conventional magnetic pole made of the Fe70Co30 alloy. However, saturation magnetization of the inver alloys are very small, e.g., 1.0 T, and their soft magnetic characteristics are insufficient, so they have not been used for magnetic poles

Which materials would generate the strongest magnetic field if used as the core?
Iron

Why do magnets stick to stainless revolvers?
This has got to do with the amount of Chrome in the alloy used to make the revolver. With a lot of chrome in the alloy, the bonds between chrome and iron would not allow for magnetic interaction. Most stainless steel is magnetic though if one just applies a strong enough magnetic force. regards.
Can PVC insulation hold the magnetic field created around a current carrying conductor?
No, to shield a magnetic field you need a magnetizable material with high permeability and low permanence. The most commonly used alloy for this purpose is called mumetal, an alloy of nickel and iron.
Why is invar often used to make accurate technical instruments that are used in hot situations?
l am so sick to death of NO ONE ANSWERING THESE stupid questions
A compass is a scientific instrument used to locate what?
A compass is a scientific instrument used to locate the north magnetic pole. The magnetic changes in the Earth's core make the north magnetic pole move over time.
What is the function of magnetic core in electrical machine?
The core, together with the machine's air gaps, form what is known as a 'magnetic circuit', which is a low-reluctance path that encloses the magnetic flux produced by its field windings, in order to concentrate that flux in the air gap through which the armature passes.
