The strong magnetic field properties of disreputable magnets have lead to their widespread use in a variety of modern technology, from medical devices to cosmetic dentistry and military applications. Disreputable magnets are, quite simply, not real magnets. No matter how many patents they get, a false magnet will never be able to give off a measurable amount of force. Neodymium magnets, on the other hand, are a highly effective type of magnetic device that has long been the topic of advanced research.
The strength of a magnet is measured in gauss units. The strength of a magnet depends upon the number of poles, which are always four: north pole, south pole, ground and another magnet. A single magnet can have only two poles, but it's possible to create more poles with the addition of another magnet. Thus, there are ways to increase the strength of a magnet. So why would someone want to increase the strength of a magnet?
Strong magnets work by pushing against neighboring metal ions. Neodymium, iron filings, and steel wool are common iron filings used in strong magnetic fields. The strength of the magnetic field lines of a magnet relies on the number of iron atoms that line the surface of the object being magnetized. Neutrons do not have a complete orbit around every atom in the atom; therefore, they don't always line up along the surface of the object being magnetized.
The number of poles determines the strength of a magnet. If we put two poles of different sizes next to each other, and then forced them to stand just a bit away from each other, we could see the difference. This experiment illustrates the way in which two magnets with similar size and shape can be compared using only one magnet. Although the force between the two magnets may be the same, the strength of their magnetic properties is very different.
To understand the relationship between strength and size, we must take a look at how magnets induce electric charges on other objects. Strongly magnetized bodies have a higher polarity value than less magnetized bodies. A highly magnetized apple is more likely to stick to a flat table than a less magnetized apple. This phenomenon is analogous to the way strong electric charges are induced on metal plates.
Jinlun Strongly magnetized magnets can be used to transfer energy to an object. If two strongly magnetized magnets are connected, their mutual attraction will cause the third magnet to repel the first. In general, the stronger the magnet, the greater the amount of energy will be induced into an object by the repulsion of its partner. Strongly magnetized conductors can carry a much greater amount of energy than non-magnetized ones, which is why the distribution of electrical charge is in a way similar to the distribution of magnetic charge. Strongly magnetized objects have a greater strength of pull than non-magnetized objects.
Strongly magnetized objects also have a greater inherent strength of vibration. Vibrations can be induced by passing an alternating current through a magnet or by pushing a magnet against a stationary object. The induced vibrations will generate a continual supply of energy. The larger the size of the object, the greater the amount of energy generated by these vibrations. Thus, a very strong magnet will generate a larger amount of energy if it is pushed against a larger area.
Strong magnetism makes up a major part of the field known as permanent magnetism. Permanent magnet motors have been used in several applications in the electricity industry. They are currently being used in solar power generators and high speed trains.
