Magnets are generally of two types: natural magnets and artificial magnets. Natural magnets are naturally occurring magnets. Loadstone is an example of a natural magnet. Artificial magnets are the man-made magnets. Horseshoe shaped magnet and Bar magnet are the example of artificial magnets.
Molecular theory of magnetism states, "If molecular magnets align in a row, then the substance exhibits magnetic property. If they are kept haphazardly, they do not exhibit magnetic property." This is the molecular theory of magnetism.
If molecular magnets align in a row, then the substance exhibits magnetic property. If they are kept haphazardly, they do not exhibit magnetic property. This is the molecular theory of magnetism. The poles of a magnet cannot be separated even by breaking into pieces because they exist in a pair and every molecule of a magnet has poles in the pair.
What is a magnet?
A substance which has the property of attraction or repulsion is known as a magnet.
What do you mean by natural and artificial magnet?
Magnet which is formed naturally is called natural magnet. Man- made magnets are called artificial magnet. For instance, Bar magnet, U-shaped magnet, etc.
What are molecular magnets?
The molecules of the magnetic substance retain the magnetic property. They are known as molecular magnets.
Why do the poles of a magnet, when broken down into pieces, not get separated from each other?
The poles of a magnet cannot be separated even by breaking into pieces because they exist in a pair, every molecule of a magnet has poles in a pair.
How does a magnet gain its magnetic property?
A magnet has molecules aligned in the same direction which provides it the magnetic property.
Why does magnet have more magnetic force at its poles than at the middle portion?
The molecular magnets are arranged in an open chain so that the north pole or the south pole of the molecular magnets lie in the same direction which gives strong force at the poles whereas two opposite poles are arranged at the middle and the force cancel each other. So, poles have more force than the middle portion.
How is the state of molecular magnets of magnetic substance laid?
Molecular magnets of magnetic substance are laid in same direction or open chain.
