  2. The Origination of Electromagnetic Theory.

  3. The Ancient Greeks’ Theory.

  4. Interest in Electricity.

  5. Electricity and Magnetism interdependence.

  6. The Importance of Electromagnetism in Physics.

  7. The Discoveries Concerning Electromagnetism.

II. Read the text. For statements (6-15) choose “True” if the statement is true according to the text, “False” if the statement is false:

  1. People in ancient Greece knew a lot about electricity.

  2. An object with an electric charge always attracts other objects.

  3. Experimenters wanted to find the interrelations between forces of nature.

  4. People knew about electricity and magnetism more than three hundred years ago.

  5. In the nineteenth century scientists considered electricity and magnetism to be quite different notions.

  6. Fluid was believed to be the cause of repulsions, attractions and other phenomena.

  7. Electricity and magnetism are thought to be very similar things.

  8. In the nineteenth century Faraday made the experiment proving a magnetic effect.

  9. Faraday’s work was the first step for the understanding of energy.
