subject: Magnetic Generator - How Basic Yet Powerful Magnetic Power Generators Can Help You Save on Your Power Bill [print this page] Clean energy is possible with a magnetic generator thanks to the inner workings of magnets. If anyone is thinking about setting up their own magnetic power generator, then it wouldn't hurt to take a look at magnets and try to get a better understanding of just what they are exactly and how they work. You might not know it but magnets and what they are made from aren't always the same. The existence of magnets has been known since ancient Greek times where magnetic fields were discovered in lodestone. Since that time, scientists have continued to examine and research them and the force and energy that their magnetic fields create.
Magnets aren't all created equal and there are actually three different kinds of magnets. One of the most common varities of magnets is the one you probably have stuck to your fridge right now called hard magnets. This kind of magnet is what most people would be familiar with. These magnets create a magnetic field all the time. They never switch on and off and they are always making a magnetic field. This ability is why fridge magnets don't suddenly fall off your fridge door. Soft or temporary magnets are another magnet variety. As you might be able to guess from the name, these kinds of magnets aren't always "on". They are able to create a magnetic field but it isn't permanent. At what times are they called magnets? These magnets create a magnetic field only when they are near another magnetic field. Only at these times are they called magnets. The final kind of magnet is an electromagnet. The presence of electricity in the wires of electromagnetic magnets creates a magnetic field.
Besides having three different kinds of magnets, there are different materials that can be used in the construction of them. The common fridge magnet is made from ceramic. Science classrooms around the world use these on a daily basis. They consist of iron oxide in a ceramic composite. These magnets aren't very powerful or strong. Alnico magnets are made from aluminum, nickel and cobalt. While this kind of magnet offers a much strong magnetic field than ceramic magnets, they are still not the strongest. Rare-earth metal magnets fall into two groups; neodymium and samarium cobalt. Rare-earth metal are the strongest magnets on the planet today
So what is the secret to how a magnet works? Magnets do what they do thanks to all of the magnetic domains within ferromagnetic materials, like iron, cobalt and nickel, pointing in the same direction. A magnetic domain is basically a small magnet in itself. Usually, the domains in these materials are not pointing in the same direction and they cancel each other out. The strength of a magnetic field increases as you align more and more magnetic domains in the same direction. This is essentially how a magnet works and why it creates a magnetic field.
Magnetic generators rely entirely on the magnetic field produced by magnets. Home owners are able to harness these magnetic fields as a source of energy to make their own home electricity from magnetic power generators. With a better understanding of why and how magnets work, you'll have a much greater appreciation of making clean home electricity with your very own magnetic generator.
