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. Magnets have been around since the Greeks discovered that lodestone attracted pieces of iron. 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? The first kind is referred to as permanent or 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. It is this that makes it possible for your fridge magnets to stay on your fridge. The second kind of magnet is called temporary or soft magnets. The name of this kind of magnet probably gives away that they aren't always "on". The magnetic field that they create doesn't last forever. Just when are these magnets "on"? These magnets create a magnetic field only when they are near another magnetic field. Only at these times are they called magnets. Electromagnets make up the final group of magnets. 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. These ceramic magnets are what you will find in schools. They contain iron oxide in a ceramic composite. These kinds of magnets aren't very strong. Alnico magnets are made of 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
Why and how do magnets work? 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 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 wouldn't work without the existence of magnetic fields in magnets. This magnetic field makes the creation of clean home power from magnetic power generators possible. Knowing the background of magnets gives you an even greater appreciate of the clean electricity you are able to create with your own home magnetic generator.
