Magnetic Fields Demystified In Magnetic Generators

Magnetic generators are able to do what they do thanks to the power of magnets

. For home owners who are considering going the parth of a magnetic power geneator, 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. Since that time, scientists have continued to examine and research them and the force and energy that their magnetic fields create.

Did you know that the power of magnets can vary and they can be made from very different matierals? Look in most kitchens around the world and you'll see on fridges the most typical kind of magnet call permanent magnets. These magnets are the general and most commonly used kind. Permanent magnets are constantly generating a magnetic field. They don't turn themselves on or off and they are always making a magnetic field. This ability is why fridge magnets don't suddenly fall off your fridge door. 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. At what times are they called magnets? Only during times when they are around other magnetic fields do they create their own. It is during these times that they are considered magnets. Electromagnets make up the final group of magnets. Magnetic fields are found in these magnets when electricity is passing through their wires.

Greatly different materials can be used in the construction of magnets. 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 kinds of magnets aren't very strong. Alnico magnets are constructed from aluminum, nickel and cobalt. Unlike ceramic magnets, these ones are actually much stronger but still don't come anywhere near the power from rare-earth metal magnets. The final group of magnets made from rare-earth metal fall into two groups; neodymium and samarium cobalt. You won't find any magnet stronger than ones made from rare-earth metal

So just 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 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 operate based on the presence of magnetic fields in 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. You'll have a much great appreciate of the home electricity you create thanks to knowing just how magnets and your magnetic generator works.
