What are magnetic regions in iron called?
Magnetic domains.
Does a magnet contains a large number of magnetic domains or poles?
POLES
Can a magnet not be magnetic?
if it truly is a magnet, than no. however, you can demagnetize a magnet by dropping it or hitting it really hard to rearrange the domains within the magnet. Domains are the regions within a magnet that have particles that are either arranged so that the poles are attracted to each other or randomly arranged so that the particles are not magnetized at all. so if it is a magnet... it probably will be magnetic unless you take your anger out on it or something.
Dropping or heating a magnet will not weaken it because the domains will stay in alignment?
False
What do domains do in a magnet?
Magnetic domains line up with each other during magnetization. Lines of force point out of the north pole and into the south pole.
When all of the magnet domains line up on their own the material is called?
a permanent magnet
Who any material that is not magnetize the magnet domains point in random directions?
The domains line up
What can cause realignment of magnetic domains in a material?
A magnet.
What do you understand by demagnetization?
De-magnetism is when a magnet is no longer a magnet. For example, when a magnet becomes heated it loses its magnetism. This is because the alignment of domains (groups of atoms) is disrupted. This is due to the expansion of the domains; the energy to expand is provided from the heat. During the expansion, the domains require more space therefore disrupting the alignment. This causes a magnet to become weaker and weaker to the point where it is no longer a magnet.... Hope this helps! :)
What is a substance in which the domains are all alingned in the same direction?
A permanent magnet has most of its domains arranged it the same direction.
Why aren't all iron materials permanent magnets?
When a magnet or iron piece is watched under a powerful microscope we will obseve that a magnet or iron is made up tiny tiny pieces which cannot be further divided realistically such small pieces are known as domains. In a magnet all domains are in the same direction due to which it attracts iron. While in a iron these domains are arranged randomly which nullify its magnetism. When a magnet is brousht near an iron matrial all the domains get attracted to the magnet due to which domains in iron get arranged in a particular direction due to wich at that time they act as magnets but as soon as the magnet gets farther the domains again arrange them selves randomly due to which tey do not remain permanent magnets
What are magnetic regions in iron called?
Magnetic domains.
A permanent magnet has magnetic properties because?
The magnetic domains are aligned
What are the small individual areas within a normal magnet are called?
domains

What can happen when you rub a magnet on a paper clip?
A paper clip is made up of iron or steel. It consists of particles called domains which are randomly arranged. When a magnet is rubbed on a paper clip, the domains arrange themselves in one direction. Thus it gets magnetized and behaves as a magnet.
