Magnets are very interesting substances found in the earth. You must already know that magnets attracts magnetic substances and repels same poles of each other. But do you know that what metals are magnetic, taking care of magnets, functions of magnet and how to magnetize metal.
Things to Remember After You Learn How to Magnetize Metal
Function of Magnet
If you are thinking that magnet attracts all metallic substances then you are wrong. A permanent magnet is found naturally in the ground but scientist has evolved new ideas to generate magnets as well as electro-magnets. The main function of magnet is to attract what metals are magnetic those have opposite dipole than a magnet.
If there are no dipoles present in a Metal then it will not get attracted towards magnet and then no need to find answer of how to magnetize metal of such kind because you can’t. For example Silver and Gold are metals but they do not get attracted towards magnet.
How to Prepare Magnet at Home
Making Magnet from Small Metallic Substance
You can prepare homemade magnet by natural process of rubbing small metallic substance on metallic surface because permanent magnet is generally referred as magnet generator. This is very simple and primary method to show you that how to magnetize metal. For example as shown in the figure if the paper clips are rubbed against surface of a magnet then the paper clips also gets magnetic and it also starts attracting other smaller metals.
You can prepare a magnet by this method only the metals those are magnetic in nature to know what metals are magnetic you should consider trying to attract them.
Making Electromagnet from a Battery
There is a property of current that when current flows in a spiral direction then it generates electro-magnetic field around the conductor from which it is flowing. The same principle can be used to prepare magnet from a battery.
When current flows from a spiral copper wire then electro-magnetic field attracts other small metallic objects and it acts like electro-magnet. Now you know another way that shows you how to magnetize metal and how to make magnet with battery.
Making a Magnet Compass
You can easily find all the four directions i.e. east, west, north or south if you have a magnet with you. As you already know that how to make magnet now you use the same method first you first need to make long thin metal a magnet by rubbing it on the surface of any magnet.
Then just suspend it free either with the help of smaller wood floating on water or with the help of very thin string. It’ll act like compass to show you direction.
Uses of Magnet in Daily Life
The principle of Electric motors is based upon the electro-magnetic field generation due to passage of current through a conductor. This is based upon the concept of how to magnetize metal by electricity passage. These electromagnetic motors are either used to convert electric energy into mechanical energy or mechanical into electric.
A shaft is prepared with help of coiling around and a magnet is placed between it so that when electricity is passed through the shaft it rotates with high speed.
In our day to day life computer plays most important role to make our work easy, neat and tidy. Every computer manufacturing company knows that how to magnetize metal and use the strength of magnetic field according to the need. A computer uses magnetic plates to store data into it. From a long time we used magnets to record music and other information through recorders and other means.
They work on the concept of changing electric energy into mechanical energy. When a charge is provided to magnetic plate, located adjacent to natural magnet, then it shakes with high speed and this whole vibration changes into sound.
Dumps and Scraps
Magnets are used to separate magnetic metals from dump and scraps so that it could be recycled. This process is used by many countries and magnets helped them to carry out these types of work. Because the sizes of such machines are too big and it is very hard to get such a big magnet so it becomes essential to know how to magnetize metal so that it can be used as magnet.
They work on same principle of attraction and repulsion of magnetic poles. When a person press button of bell then current flows through the coil of the bell which makes the coil act as magnet and attracts and repel magnetic metals those creates sound.
World’s fastest bullet trains Maglev trains are based upon the concept of magnetic repulsion of same poles of magnet. The track of trains are too long so it would be good to know that how to magnetize metal so that it would be used on tracks. Track of these trains are designed such that it repels the train due to which train stays above the track without touching it. This reduces friction and increases speed of the train.
It works on the phenomenon that earth has two poles and earth is also producing magnetic field every time from North Pole to South Pole. This is the reason if magnet is suspended freely in the air then its S Pole tends to move towards North Pole
If there were no magnets then we would have to use a door lock in refrigerator. Only magnets are the substances those has provided us to keep our refrigerator air tight closed by sticking to the magnetic metals of the fridge. The magnets are used at corners of every refrigerator so that it keeps doors closed.
How to Take Good Care of Magnets
Pack Them Properly
Magnets repel same poles of each other which make them to be very useful in many places. After you get knowledge about how to magnetize metal you should consider placing it properly. This property of natural magnet would be lost if they are not packed properly.
For example if two magnets with are kept together with different poles adjoining then they would soon loss their magnetic property and they would not be magnet anymore. Two magnets should be packed with a gap of 1 inch between them and same poles should be in one direction.
Magnets are very entertaining and useful substances found in the earth. We can also produce magnets in a huge quantity to complete our needs and wants if we know how to magnetize metal.
It is very easy to make any electro-magnetic substance but a natural magnet can’t be found easily. Either they are formed in a factory or found naturally if you also have a natural magnate then you should take a very good care of it.
