How is an unmagnetized piece of iron different from the same piece of iron when it is magnetized?
An unmagnetized piece of iron has its atoms pointing in different directions, and opposing each other. When the iron is magnetized, the atoms are mostly pointing in the same direction, and the fields add together.
What is the difference between a soft iron bar and magnet structure?
A soft iron bar can be magnetized temporarily in the presence of a magnetic field and loses its magnetism once the field is removed. A magnet structure, on the other hand, retains its magnetism even without an external magnetic field due to its aligned atomic structure.
What is the difference between magnetic materials and non-magnetic materials?
Magnetic materials are materials that can be magnetized and can create a magnetic field, such as iron and nickel. Non-magnetic materials do not respond to magnetic fields and cannot be magnetized, such as wood and plastic.
Can iron be magnetised?
Yes, iron can be magnetized. When exposed to a magnetic field, the magnetic domains in iron align to create a magnetic field of its own. This causes iron to exhibit magnetic properties.
Which orientation characterizes the magnetic domains in an unmagnetized piece of iron?
In an unmagnetized piece of iron, the magnetic domains are randomly oriented. This means that the magnetic moments of the atoms within the domains are pointing in different directions, resulting in no overall magnetic field being exhibited by the material.

Can a magnet attract to a demagnetized iron rod?
Yes. In this case, the magnet will induce magnetism in the iron, which is originally unmagnetized. Once the magnet is removed, the iron may return to an unmagnetized state; unless the magnetic field near the piece of iron is very strong.
Would two iron bars attract?
No, two iron bars would not attract each other under normal circumstances. Iron is a ferromagnetic material, meaning it can be magnetized, but two unmagnetized iron bars will not exhibit a magnetic attraction. However, if one or both bars are magnetized, they can attract or repel each other depending on their magnetic orientation.
What is the difference between magnetic materials and non-magnetic materials?
Magnetic materials are materials that can be magnetized and can create a magnetic field, such as iron and nickel. Non-magnetic materials do not respond to magnetic fields and cannot be magnetized, such as wood and plastic.
Why a magnet attracts an unmagnetized iron?
Iron is a magnetic element therefore it will be attracted by a magnet.
When was magnet founded?
It was in around 1734, that Swedenborg, a Swedish scientist brought to notice the differences between a magnetized piece of iron and an unmagnetized one. The magnetic substance that was discovered for the first time ever was magnetite. But Louis Neel, a French physicist disapproved this discovery by coming up with the concept of ferromagnetism.
How does iron differ in a magnetised and unmagnetised material?
In a magnetized material, the iron atoms align their magnetic fields in the same direction, creating a net magnetic field. This allows the material to attract or repel other magnets. In an unmagnetized material, the iron atoms have random magnetic orientations, resulting in no net magnetic field.
Will iron stick to the south or north of a magnet?
It will stick to either pole, providede that the iron is not magnetized and that it is not above the Curie temperature (the temperature above which iron can no longer be magnetized, named after Marie and Pierre Curie).
