Buy Strong Magnets Application In Cutting Edge Magnetic Resonance Imaging

This is how mankind came to know of magnets: Magnes the shepherd got his metal staff and the nails in his shoes stuck to a strange rock near Magnesia in ancient Greece. Since then, magnets have found a lot of uses in modern day civilization. Such is the attractive power of magnets that some people buy strong magnets for their private collections.

What Is A Magnet?

In layman's terms, a magnet is an object that pulls and attaches itself to certain metals and repels others. A magnet can be made from a variety of materials such as cobalt, nickel, steel and iron. The easiest way of produce a magnet is to have these materials placed in a magnetic field produced by a powerful magnet. This is the basic method of producing temporary magnets as well as permanent magnets. Temporary magnets are made from materials that are easy to magnetize such as Permalloy (nickel and iron mixture) and iron alloys.

Permanent magnets, on the other hand, are made from ferrites such as iron oxides and alnico which is made of cobalt, iron, nickel and aluminum. Electromagnets are made from strong magnets. They consist of a metal core placed inside a current carrying coil. Superconductors are the last category of magnets and the strongest. These are magnets made from super cooled wire coils that are fabricated from special alloys.  

The strength of a magnetic field is measured using the Tesla (T) and the Gauss (G). 1T = 10,000G. The earth is one large magnet measuring 0.5G. This varies based on your exact location. The field is weakest at the equator and strongest at the north and south poles. If are fascinated by magnets, buy strong magnets especially neodymium magnets are observe the real power of magnetism at close range.

Magnets And Magnet Resonance Imaging (MIR)

Among the many uses of magnets, MRI is one of the most revolutionary. Magnetic Resonance Imaging is a medical procedure that is used for patient imaging. It requires strong radio waves and magnetic fields in order to generate images of internal structures and organs. These images are usually of the cross sectional type. According to the U.S Food and Drug Administration (fda.gov), neodymium magnets are the best for conducting MRI.  

MRI machines make use of the varying signal that is detected back by the machine to come up with these images. This signal depends on the magnetic property and water content of the body area being examined.MRI procedure produces more detailed images as compared to Computed Tomography (CT) scans, ultrasound and standard X-ray.   

You can buy strong magnets from credible online retailers or department stores. However, read and observe the safety instructions to the letter as strong magnets are capable of breaking hands and finger bones as they attempt to stick together.
