  1. Generators, AD & DC Power

  2. Unit Standards

  3. How can magnets produce electricity? • Generator- a device that creates electric current by spinning an electric coil between the poles of a magnet.

  4. How can magnets produce electricity? • Energy is used to turn the axle of the generator. • As the coil moves through the magnetic field, forces push on its electrons and create an electric current. • Wires attached to the loop allow the current to flow as the loop rotates.

  5. How can magnets produce electricity? • Whenever a loop moves past the pole of a magnet, the direction of the magnetic forces changes. This causes changes in the direction of the electric current.

  6. How can magnets produce electricity? • Alternating current- electric current that rapidly changes directions • Direct current- electric current that flows in one direction.

  7. How can magnets produce electricity? • In generators, there are several coils of wire that spin past many magnets. US generators produce alternating current that changes directions 120 times a second.

  8. How can magnets produce electricity? • Nikola Tesla was born in 1856 in Smiljan, Croatia, then part of the Austro-Hungarian Empire. • Some of his inventions: Alternating current, how light was harnessed and distributed, X-rays, radio, remote control, electric motor, robotics, lasers, and wireless communication
