Mineral Magnetism - The Laws Of Attraction
The pull of magnets captures the imagination of many when still in the early formative years. The look of amazement on the face of a child when introduced to a magnet is a sight to behold, as magnets truly are one of the only things in the natural world that gives every appearance of magic. The study of magnetism and its effects on the world around us is an ever-growing field of research, ever pushing the limits of our technology beyond the previous boundaries of reality only bound by our imagination. Neodymium magnets take that boundary to a new level by bringing us magnets of unbelievable strength and function.
This may sound a bit far-fetched, but the truth is that magnetism lies at the core of nearly every bit of technology we take for granted today. From the generation of electricity to the various applications of technology that utilize that electricity, magnets and magnetism are a huge part of the world we live in today. Even the memory chips in your computer and media player use magnetic particles to hold switches in on or off positions, keeping our records and entertainment firmly held in its magnetic grasp.
Neodymium magnets, the most widely used rare-earth magnets, are man-made alloys that have a very high remanence factor, as well as a high coercivity, meaning they hold a very strong magnetic charge, and are able to hold on to that charge, not being easily demagnetized. This is important in many applications where magnets are needed to perform important functions. Magnetic resonance imaging (MRI) machines are highly dependent upon highly magnetic compounds and with the cost of the machines being what they are it is important for that magnetism to remain for a great deal of time.
Electricity not only is created by moving a conductor through a magnetic field, which is how generators work, but electricity and magnetism are so closely related that every flow of electricity creates an inherent magnetic field by the simple flow of electrons through a conductor. The relationship, though obvious and more than evident is still something of a mystery. With all of our technological advances, we still need to expend large amounts of energy creating electricity. Free energy is still a long way off if it will ever be a reality, even though by all appearances the new high-powered magnets would induce instant and nearly free electricity. The motive forces necessary to move the conductors are always going to be an issue.
Neodymium magnets have such strong magnetic force that if you were to place your hand between two neo magnet discs at four inch diameter and one inch thick, your hand would be crushed horribly. These magnets are so strong that they are actually dangerous. Remember that if you are ever handling them, you should be sure to exercise caution and be very mindful. What was once a child's toy has become a very powerful tool, and powerful tools should be treated with respect.

Magnetism For The 21st Century And Beyond
If you do not remember learning about magnets in the fourth grade then you probably have never heard of rare earth magnets. These types of magnets are not rare in the traditional sense, but rather they are alloys fashioned from some of Earth?s common elements, such as iron, boron, and cobalt. They were originally developed in the 1970?s and 1980?s. They are stronger than all other permanent magnets, and their magnetic field is almost twice as intense as any other magnet found today. However, they tend to be very fragile, and they oxidize just as easily. Therefore, they are often coated with gold or nickel for protection.
All magnets, including rare earth magnets, are created when their electrons line up in the same direction creating a single magnetic field that surrounds the entire object. Most magnets used everyday, such as horseshoe and bar magnets are permanent magnets, as are rare earth magnets. They are referred to as permanent, because they keep their magnetism for a very long time. There are also natural rock magnets, such as lodestone, but this is also very brittle and easily broken. If one of these natural magnetic rocks or alloy magnets are not protected, and are broken their electrons are knocked out of alignment thereby disrupting their magnetic fields.
When rare earth magnets were first invented, they were very expensive and hard to find. However, they are currently massed produced and are easily located by the common person. Generally, there are two types that are used commercially and can be purchased by anyone: samarium-cobalt and neodymium. Samarium cobalt is reasonably priced, but its attraction is not as strong as neodymium. However, it has a strong resistance to oxidation. Neodymium is composed of iron and boron, and it has a much stronger attraction, but it easily oxidizes. Both these alloys are encased in an epoxy resin, gold, zinc, or nickel for protection.
Rare earth magnets can be found in cordless tools, hard drives, and speakers. More recently they can be found in building toys for children. They have also become a fixture for the hobby enthusiast and model makers. They use them to help create long lasting reproductions of everything from tanks to airplanes. There are also those industrialist individuals who claim rare earth magnets can be used to create the mysterious perpetual motion generator. This is a generator that reportedly uses very little energy to produce a tremendous and long lasting power source for home and industrial use. This type of magnetic has proven to be versatile and necessary for many businesses especially the computer and electronic fields. It seems that without this item society would not be able to compute, chat, or even function.
