If anyone is thinking about setting up their 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. Magnets aren't by any means new and they have been known about since Greek times. It was from that time on the mystery and power of magnets has been probed, researched and constantly amazed young children.
Magnets come in all shapes and sizes and the strength of their magnetic fields and materials they are made from can vary. The first kind is referred to as permanent or hard magnets. This kind of magnet is what most people would be familiar with. These magnets create a magnetic field all the time. There is no on and off switch and they are always making a magnetic field. This ability is why fridge magnets don't suddenly fall off your fridge door. Beyond hard magnets, there is another kind called temporary magnets. 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. 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. The final kind of magnet is an electromagnet. The presence of electricity in the wires of electromagnetic magnets creates a magnetic field.
Greatly different materials can be used in the construction of magnets. Ceramic magnets are the kind stuck to your fridge. Science classrooms around the world use these on a daily basis. They contain 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. These two groups of magnets offer the strongest magnetic fields known to this day.
Why and how do magnets work? When you point all the magnetic domains in magnets in the same direction, you experience the effect that magnets have. A magnetic domain is basically a small magnet in itself. Most of the time, the magnetic domains in iron and other magnetic materials aren't aligned and they cancel each other out. The higher the number of these domains that point in the same direction, the stronger the magnetic field of the magnet 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. It is this magnetic field that allows magnetic power generators to create electricity using a source of energy that doesn't pollute or produce large amounts of harmful by products. You'll have a much great appreciate of the home electricity you create thanks to knowing just how magnets and your magnetic generator works.
