Types of Magnets Objects having magnetic field is called as magnets. Normally magnets are of two types- Permanent magnets and Electro magnets. Permanent magnets are those magnets which occur in nature and do not depend upon external source for their magnetic field. On the other hand electromagnets are those magnets which use electric current to generate magnetic field. Classification of Magnets There are different types of magnets with different physical and magnetic properties and strength

Neodymium magnets are used for many purposes. They are used in industries‚ commercially and can even come handy around the house. Neodymium magnets are also used in the Medicine and Health fields for a large number of purposes. Industrial Uses Of Neodymium Magnets Neodymium magnets are often used in machines made for the health industry. They are also used for magnetization‚ to make magnetic separators‚ magnetic filters and for magnetic ionization. The security industry uses them for alarms and

Common uses of magnets Hard disks record data on a thin magnetic coating. • Magnetic recording media: VHS tapes contain a reel of magnetic tape. The information that makes up the video and sound is encoded on the magnetic coating on the tape. Common audio cassettes also rely on magnetic tape. Similarly‚ in computers‚ floppy disks and hard disks record data on a thin magnetic coating. • Credit‚ debit‚ and ATM cards: All of these cards have a magnetic strip on one side. This strip encodes

was “The Magnet Rifle”. I am going to now tell you all of the research that I have done for my experiment. “What is a Magnet?” A magnet is a piece of iron and it has its own component atoms. One magnet can attract other iron‚ ore and even alloy. But the objects have to be containing one of those materials so it an come together. If two magnets align it it is considered to be called a magnetic field. Compasses are used by magnetic fields coming from the North and South Poles. The way magnets come together

Magnet Schools: An Opportunity of Education or Education Disparity? We are often put into situations that are not fitting of us and it is up to us to either get out of the situation or make the best of it. Parents want their children to receive quality education but sometimes a child is placed into a school that doesn’t have a curriculum challenging enough for a student. Luckily‚ there are other avenues for us to take in order to get a quality education without the cost of a private school or
