Relationship between electricity and magnetism How the electricity is Generated
Ciudad de Magnesia en Asia Menor. 2,500 A.C Natural stone, Called Magnetita North Pole and South Pole. The Chinese people used a magnetic needle to build the compass. Sailed Iron filings Magnets made by an industrial process
With the discovery and development of electricity Hans Christian Oersted Right hand rule Thumb
Coil with N Turns
Similarity between a permanent magnet and a coil with Electrical Current. (Electromagnet)
ElectroMagnet
When an electric current circulates within a magnetic field, the magnetic forces produce a torque that causes the spiral to rotate. Electric motor
The opposite process The blue line represents the magnet coming out of the coil The red line represents the magnet entering the coil
producing current with a generator
Mechanical shaft Diferent ways to Generate Alternate Current Hydroelectric dam
People create dams and the force of falling water moves some blades that are connected to the rotor that are permanent magnets. when the permanent magnets move in the windings, an alternating current is induced and this is sent to a transformer to raise it´s current and transport it by cables to the big cities
