Magnets and Electromagnets - you
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron ; the magnetic core concentrates the magnetic flux and makes a more powerful magnet. The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding.Consider: Magnets and Electromagnets

This makes the charges in the metal loop move in a current in the same way a moving magnet would. The current in the metal loop makes its own magnetic field which opposes that of the big electromagnet. |

Magnets and Electromagnets
We are reading a lot on the Web about magnetic generators and their ability to generate free energy.
The idea that we can generate our own electricity simply by building a device using inexpensive magnets is absolutely amazing. I have seen them called electromagnetic generators, permanent magnetic generators, perpetual magnetic generators and magnetic power generators.
Permanent magnets can be made out of many different naturally occurring substances of which magnetite is the most powerful. They can also be made out of synthetic substances such as neodymium. A neodymium magnet is the strongest type of permanent magnet and is sometimes described as a super Electromzgnets. The electromagnet was invented in by Magnets and Electromagnets Sturgeon, a British electrician.
He demonstrated that a seven ounce piece of iron that was wrapped around with wires and had a small electrical current running through it could lift nine pounds of metal. If there is no flow of electricity through the wires then it does not work. The magnetic generator however uses the rotating magnets to generate electricity in the first place. It generates more energy than is required to keep the Magnets and Electromagnets rotating and so you can use the excess to power your home. The plans that we see on the web detailing exactly how to build your own magnetic power generator use permanent magnets not electromagnets.
