If the south pole of a strong magnet brought an iron nail the domains in the nail will be oriented randomly?

No. There is some randomness, but it is dominated by a very strong tendency for the domains to be oriented towards the poles, along the lines of magnetic force.

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.
Is the magnetic field the area around the magnet where the force acts?
Magnetic domains are microscopic areas of a solid where the atoms all have their magnetic moments aligned. If these domains are randomly aligned then a ferromagnetic material like iron or nickel will not have any permanent magnetism. If these domains start to align with each other the bulk material will show permanent magnetism. The area around a magnet where the force acts is the magnetic field.
What are magnetic regions in iron called?
Magnetic domains.
Does a magnet contains a large number of magnetic domains or poles?
POLES
Dropping or heating a magnet will not weaken it because the domains will stay in alignment?
False
What would happen if a strong magnet passed an object with magnetic domains arranged randomly?
most of the domains line up so that the north pole of the object is attracted to the south pole of the magnet.
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 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.

Why does a magnet lose strength each time you drop it?
The magnetic poles of the magnetic domains are physically jarred and realign. They realign randomly. When a material appears to be strongly magnetized it is because these domains are aligned.
What is molecular theory of magnetism?
all the molecules of a magnetic substance is an independent magnet. in an unmagnetized magnetic substance, the molecular magnets are randomly oriented. they form dosed chains so they neutralize the effect of each other. these chains are called domains and each molecular magnet is called dipole. when a substance is magnetized, the molecular magnets are arranged in one direction by breaking the domains. the end where all the north poles of the dipoles are present becomes the north pole of the magnet. the other end where south pole of the dipoles are present becomes the south pole of the magnet. when the magnet is strongly heated or hammered the kinetic energy of the molecules increases and therefore the molecules alignment gets disrupted and the molecules go back to the closed chain arrangement to form domains and thus the magnet gets demagnetized :) thank you.
How is the arrangement of domains different in a magnetised and a non magnetised piece of iorn?
In an unmagnetised piece of iron, these magnetic domains are arranged randomly and point in lots of different directions - they cancel each other out. In a magnetised piece of iron, all these domains point in the same direction. This makes one end of the magnet act as a north pole and the other end act as a south pole. The better the domains are aligned, the stronger the magnet. Bye bye!
How can you destroy a magnet?
If you take a permanent magnet and heat it up past the Curie temperature (or Curie point, Tc) and cool it, the magnetic domains in the magnet, which were aligned when it was made, will become randomly oriented. When the "magnet" cools, its magnetic properties will have "disappeared" and the you'll have a piece of metal alloy. If you like, you can make a new magnet out of your hunk of metal by heating the metal past the Curie point again, applying a static magnetic field to it, and then cooling it back down in the presence of the magnetic field. That's the way the magnet was manufactured and made into a magnet to begin with.
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! :)
