A Discovery of the rare-earth element

It is the amazing magnetic field which exists behind almost every technological device used for the modern commercial, industrial as well as household purposes. The rare earth elements used in the advanced motors, generators and computers to minimize the use of electric power is nothing but the earth magnets. It possesses the magnetic field similar to the permanent magnets. That means it is almost impossible for these magnets to demagnetize. Only heat is the core enemy of the magnet. A neodymium can lose its magnetic power in elevated heat. In fact the magnets are so strong and powerful because of the raw metal used to make them tremendously powerful.

The earths magnets are made of the material called ferromagnetic metals, which, when magnetized can generate a strong magnetic pull. This magnetic pull or magnetic field is responsible for the attraction of the metal. It is so powerful that it can crush your finger if it comes between two magnets. Often it can become the reason of serious health complications if swallowed by little children. So it is advisable to keep it away from the reach of the kids. Though magnets are the metal of fun, but children should not be allowed to play with it. A few preventive cautions are there which should be followed to safeguard you from the hazard of the metal. While handling big strong magnets it is wise to cover your eyes and hands with proper protection. Neodymium is a brittle metal so while machining there is a chance of breaking of the magnet and the tiny particles of the metal can fly in airs which are not less sharp than glass particles. These magnets can even break if dropped from the hand.

In the later years of 1900, Earth magnets were discovered. Since that day researches are going on to produce more and more strong magnets. The permanent magnets can be used for scientific, commercial, industrial and household applications. the Neodymium magnets are safe and affordable. That is the reason it is widely used by school children in their various science experiments. It has a wide usage in household application also. In the scientific community it can be used in the mechanism of self-powered flashlights, computers, cordless devices, in different electronic devices, refrigerator, washing machine, microwave and the like. All the electromagnetic devices rely on magnets for their function. Starting from the hard drive of a computer to the magnetic credit card, all functions with the power of magnets.
