Iron can be demagnetised by heating for an extended period of time.
_______________________________________________________________
You have to melt it and and allow it to re-solidify and it will be demagnetized. If you heat it to near melting and allow it to stay that hot for awhile then it will demagnetize of time (this is because bits of it will be hot enough to melt and demagnetize and that heat will disperse somewhere else to demagnetize a different spont).
The temperature at which a ferromagnetic material, which is a material that retains an applied external magnetic field (like iron), loses its magnetization is called the Curie temperature.
Non-magnetic iron can become magnetic through a process called induction. This can occur when the non-magnetic iron is placed in a magnetic field, causing its atomic dipoles to align and generate a magnetic field of its own. Heating the iron to a certain temperature, known as the Curie temperature, can also lead to the induction of magnetism.
In a magnetic material that is not a magnet, magnetic domains are arranged in random fashion canceling the net magnetic field. If such a material, like an iron rod, is exposed to a strong magnetic field, the domains will arrange themselves in the direction of the applied field and hence object will become magnetized.
Take a magnetizable material (such as iron, cobalt, or nickel), and use this as your core.
Wrap copper (or other conductive metal) wire around the core material.
Once you pass electric current through the conductive wire, a magnetic field will form perpendicular to the wire coil, which will induce a magnetic field in the magnetizable core material...thus magnetizing it, turning the entire assembly into an electromagnet.

What is a example of induced magnetism?
An example of induced magnetism is when a non-magnetic material, like iron, becomes temporarily magnetized when placed near a magnetic field, such as a bar magnet. The alignment of the atomic dipoles in the material causes it to exhibit magnetism, but it loses its magnetism once removed from the magnetic field.
What is induced magnetism?
Induced magnetism refers to the temporary magnetism that a material can acquire in the presence of a magnetic field. When a material is placed in a magnetic field, its atomic or molecular magnetic moments align with the external field, creating a temporary magnetization. This effect disappears when the external magnetic field is removed.
What is the sure test of magnetism?
The sure test of magnetism is the ability of a material to attract iron or other magnetic materials. If a material attracts iron, it is considered to be magnetic.
What mineral property involves iron?
Magnetism is a mineral property that involves iron. Iron-containing minerals like magnetite and hematite are naturally magnetic and can attract other materials like iron filings.
Which pole of a magnet is attracted to iron?
Any of the two poles will work. It will induce magnetism in the iron.
How high the magnetism of platinum?
Platinum is Nonmagnetic.
What is affected by a electromagnet?
Other magnets, as well as magnetic substances such as iron, in which magnetism is induced by the external magnetic field.
What is affected by electromagnets?
Other magnets, as well as magnetic substances such as iron, in which magnetism is induced by the external magnetic field.
What is Gilbert experiment?
There are several experiments known as Gilbert's Experiment, but the most common is in induced magnetism. This showed that an piece of iron became temporarily magnetic when placed on a magnet. This is why sprinkled iron on a paper over a bar magnet seems (but actually does not) show magnetic lines of force. Instead the iron particles just obey Gilbert's Law of Induced Magnetism.
How can be induced?
You can induce magnetism by heating it.
Why is magnetism induced into an iron bar placed near a magnet?
When an iron bar is placed near a magnet, the magnetic field of the magnet aligns the magnetic domains within the iron bar. This alignment increases the overall magnetic field strength of the iron bar, effectively inducing magnetism in the bar.
Magnetism can sometimes be in an iron object by rubbing it with a magnet?
Yes, this process is known as magnetization. When an iron object is rubbed with a magnet, the domains within the iron align in the direction of the magnetic field created by the magnet, causing the iron object to become magnetized.
What are 5 examples of magnetic forces?
polarized atomic regions (a magnetic substance) electron-induced magnetism (induction) radio-induced magnetism (radio waves induce current on a conductor that in turn is creates electron induced magnetism) reverse-magnetostriction (the opposite of the effect that states magnetism causes metal to change shape on the atomic level) a flawless LRC circuit

How does the process of electromagnetic induction work?
The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.
What property involves iron?
Magnetism involves iron.
