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. Did you know that there are actually many kinds of magnets and they can be constructed from different materials? 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. Look in most kitchens around the world and you'll see on fridges the most typical kind of magnet call permanent magnets. This kind of magnet is what most people would be familiar with. Permanent magnets are constantly generating a magnetic field. 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". The life of the magnetic field they emit doesn't last forever. Just when are these magnets "on"? Only during times when they are around other magnetic fields do they create their own. Only at these times are they called magnets. The final kind of magnet is an electromagnet. These magnets only produce an electric field when electricity is traveling through their wire coils.
Besides having three different kinds of magnets, there are different materials that can be used in the construction of them. The magnet on your fridge is made from ceramic. Science classrooms around the world use these on a daily basis. They are made from iron oxide in a ceramic composite. Ceramic magnets are the weakest kind. Alnico magnets are made from aluminum, nickel and cobalt. Alnico magnets are much stronger than ceramic magnets but are still weaker than magnets made from rare-earth metal. 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 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. 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 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. 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.
