If you are seriously considering putting together your own magnetic power generator, then knowing the history of magnets, what magnetic fields are and how many different kinds of magnets there are will only make your jub much easier. There are actually many different kinds of magnets and they are all made using completely different materials. The existence of magnets has been known since ancient Greek times where magnetic fields were discovered in lodestone. It was from that time on the mystery and power of magnets has been probed, researched and constantly amazed young children.
Did you know that the power of magnets can vary and they can be made from very different matierals? One of the most common varities of magnets is the one you probably have stuck to your fridge right now called hard magnets. These magnets are the general and most commonly used kind. Permanent magnets are constantly generating a magnetic field. They never switch on and off and they are always making a magnetic field. This allows fridge makes to stay stuck to the fridge without falling off. The second kind of magnet is called temporary or soft magnets. It might already be clear that these magnets aren't always creating a magnetic field. The life of the magnetic field they emit doesn't last forever. So when are they considered magnets? Only during times when they are around other magnetic fields do they create their own. Only at these times are they called magnets. The third kind of magnet is an electromagnet. Magnetic fields are found in these magnets when electricity is passing through their wires.
In addition to there being three kinds of magnets, magnets can also be constructed from very different materials. Ceramic magnets are the kind stuck to your fridge. Science classrooms around the world use these on a daily basis. They are made from iron oxide in a ceramic composite. These magnets aren't very powerful or strong. Alnico magnets are constructed 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. The final group of magnets made from rare-earth metal fall into two groups; neodymium and samarium cobalt. These two groups of magnets offer the strongest magnetic fields known to this day.
So what is the secret to how a magnet works? Magnets make electromagnetic fields because all the magnetic domains in them are aligned in the same direction. A magnetic domain is basically a small magnet in itself. Typically, the magnetic domains in iron and other magnetic materials aren't aligned and they cancel each other out. The more magnetic domains you have in the same direction, the more powerful the magnetic field is. 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. This magnetic field makes the creation of clean home power from magnetic power generators possible. 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.
