Strong Magnets And Their Applications

Magnets, or materials that exude a magnetic pull, possess some of the most intriguing properties in the universe. The materials that emit these magnetic fields as diverse as their counterparts that are drawn in by their force. The average person is introduced to the concept of a magnet in childhood, when they witness colorful thingamajigs of all shapes and sizes stuck to the refrigerator, holding up papers of varying importance. However, most of us do not understand exactly why this phenomenon happens.

Anything that produces a magnetic pull or field is considered a magnet. Although it is not visible to the naked eye, this property draws metals and materials toward the magnetic field. The magnetization of a material, or the strength of it's ability to pull in other objects, may be subject to change over time. Strong or permanent magnets create their own sustained magnetic fields. Examples of strong magnets range from refrigerator magnets to any commercial toy magnets.

The history of magnets dates all the way back two thousand years ago to the civilizations of Ancient India, China, and Greece. One of the first uses for magnets was to direct the traditional compass. Not many people know that true magnetic north is not the same direction that a compass points. If you follow a compass all the way north, it will take you to somewhere just above Canada, rather than the North Pole.

Not only do magnets allow parents to showcase their children's artwork on their fridge, but they also are used in construction to move materials with cranes. Electromagnets are charged with the task of generating electricity in wind turbines. Some magnets are used to quickly sort items by drawing all of those with metallic properties or that respond to the magnetic pull to one point. This is commonly applied for use in landfills. As said before, magnets help us to find our way through the world by pointing us in the right direction in compasses. Magnets are even used in medicine from time to time. The once rarely recognized property of materials has become a key component of industry and business throughout the world.

Strong and permanent magnets are one of the wonders of the world, but so are their weaker counterparts. This attractive, invisible force displayed by materials has become something extremely important for the functionality and success of industry, and even, society as a whole. Although knowledge of magnetic properties have been around for over two thousand years, new uses for magnets are being discovered every day. The concept that magnets are a simple child's science fair project has been broken time and time again, and will continue to happen as science becomes more and more advanced. They lift weighty loads quickly without hooks or harnesses, and easily sort through junk to find usable magnetic metals. If you ever look at that fridge and wondered exactly what your decorator fridge magnets counterparts are capable of, these examples surely shatter all expectation.
