1 Relationship between electricity and magnetism How the electricity is Generated

2 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

3 With the discovery and development of electricity Hans Christian Oersted. 1820 Right hand rule Thumb

4 Coil with N Turns

5 Similarity between a permanent magnet and a coil with Electrical Current. (Electromagnet)

6 ElectroMagnet

7 When an electric current circulates within a magnetic field, the magnetic forces produce a torque that causes the spiral to rotate. Electric motor

8 The opposite process The blue line represents the magnet coming out of the coil The red line represents the magnet entering the coil

12 Mechanical shaft Diferent ways to Generate Alternate Current Hydroelectric dam

13 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
