Making Sound: Magnets

When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. This changes the magnetic forces between the voice coil and the permanent magnet, moving the coil and attached diaphragm back and forth.

So how does the fluctuation make the speaker coil move back and forth? The electromagnet is positioned in a constant magnetic field created by a permanent magnet. These two magnets -- the electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent magnetic field, and the negative pole of the electromagnet is repelled by the permanent magnet's negative pole. When the... Read more

Free Energy Generators

The Magnet motor (or magnet engine) free energy generator is a decent, powerfull and well-looking topology of a free energygenerator. It works on a principle of the powerfull neodymium permanent magnets. When the magnetic force reachs the necessary level to overcome the friction, the motor RPM ramps up and reachs the equilibrum value. In the ordinary motor, the magnetic field is generated by the electric coils, usually made of copper sometime

s an aluminium (Al). Because both copper and aluminium are not superconductors (their resistance is not zero), the ordinary electric motor continuously needs the electric power to maintain the magnetic field. I repeat: The ordinary motor needs not only the initial energy, but the coutinuous supply of energy!... Read more
