Lets Learn all about the basic of Magnet!
‘What is magnet’ is explained here with lots of examples, types, explanation, characteristics to have a piece of good knowledge. I hope, you will enjoy this session.
What is magnet? A very common question! All kids are playing with magnets. Even senior people are also fond of magnets and they get this object they also tend to ply. We all have fridge magnets and it’s very interesting when we stick it on the fridge. We have brought so many symbolic fridge magnets from various countries.
In our home, we see,
In big heavy industries, like various vehicles, generators, cranes, etc. magnets are widely used. We have learned that magnets are the main object in the campus.
I remember an event in my childhood. I was 5 years old and suddenly got an object. I was playing with it but totally surprised to see the behavior of it. It was attracting other objects.
I keep the object in touch with:
In the above all cases, I had seen the object is attached. Then I try to keep it with some other objects like
In these cases, I had seen the object is not attached. Again, I try to keep it to attach to the fridge. It is attached. This behavior is not normal of the materials and the concept of magnet comes.
Why the objects are behaving differently from various objects? We have seen in the above example:
This object creates an effect that attracts the iron and this object which attracts iron is called a magnet and the effect is called as magnetic field.
We can define as,
”An abject that can attract other objects by creating a magnetic field, is known as a magnet.”
Magnets are of different shapes:
|Shape of Magnets|
|Shape Is Like Bar||U Shape||Ring Shape||Disc Shape|
|Bar Type||U Shape Type||Ring Type||Disc Type|
There are a few terms that are required to know for the understanding of magnet. These are.
Each magnet has two ends. Magnets have two poles:
When the magnet comes close to pins or iron nails, it will be attracted. Why does this attraction happen? Because it always produces an effect around it which helps to attract. This effect is known as the magnetic field.
Two opposite poles are attracted. It means:
Two same poles repel each other. It means:
It attracts the following metals:
The basic properties of magnets are, as follows:
It’s all about 4000 years ago. Do you believe it? There was a small place Magnesia in northern Greece. A person Megnes lived in that place. He was a shepherd and had a herd of sheep. This place was having a range of mountains and it’s very beautiful. He had always one iron stick in his hand.
One morning, he was herding his sheep and suddenly he found that his iron rod sticks with one rock.
He was totally surprised and thought about how was it possible. Now, Magnes was very dynamic and thought he has to find out why this abnormality happened?
He brings awe and started digging. Continuous digging helps him to find out an abnormal rock that sticks the iron rod.
He checked with his iron stick continuously. When he brings his iron stick near to the rock, the rock attracts. If it brings very near to the rock, it attracts fast. If it maintains little distance from the rock, the stick attacks slowly.
This is the abnormal behavior of the rock.
This abnormal rock is nothing but a magnet and this is a real story of the discovery of magnet.
Pliny the Elder, a Roman author as well as naturalist researched on a hill in the early A.D. years. He proved and documented that the hill was made of a specular stone which attracts iron. Pliny, later on, described it as the magical powers of magnetite and launched few theories.
Initially, when the magnet was not discovered, to understand direction, the following techniques are used,
In China, around 800 A.D, the Chinese are developed a compass to navigate in the sea considering loadstone and its magnetic properties.
In the same way, magnets are introduced in Scandinavia, France, England, Denmark, India, etc.
In 1983, scientists have produced magnets of the advanced magnets, i.e., 35 MGOs and currently it is developed to 52 MGOe magnets.
In this era, we cannot move an inch without magnets. It is used by a small fan of big machines.
Following are the few uses in our life:
There are few things, which should not do with magnets to protect the magnetic property. The following things which lose the magnetic properties,
So, we have learned the basics of magnets. I hope, the idea is clear, please write to us, if you have any doubt.
