Solution

Michael Faraday's main inventions & discoveries:

  1. Electric motor: In 1822, Faraday invented the first electric motor.
  2. Electromagnetic induction:
    Faraday's discovery of electromagnetic induction was published in 1831. He built a simple transformer in a well-known experiment. By winding two distinct lengths of wire around opposing sides of an iron ring, he created two coils. One coil was attached to a galvanometer, and the other to a battery. He noticed the galvanometer beat as he attached and unplugged the battery. Mutual induction is the name given to this event, and it is the foundation for transformers.
  3. Electromagnetic generator:
    Faraday combined the knowledge of electromagnetism and motors to create a generator. He studied magnetic lines of force and concluded that the magnitude of currently created by moving magnets was related to the speed of motion and the number of lines of force severed by the motion. He created the Faraday disc, which was the first electromagnetic generator of electricity, and it converted mechanical energy into electrical energy.
  4. Discovered Benzene:
    Faraday's first findings were in the field of chemistry. Hexachloroethane, C2Cl6, and tetrachloroethane,C2Cl4, were the first known synthetically manufactured carbon and chlorine compounds in 1820. He made benzene C6H6, a crucial molecule in modern chemistry that also served as the foundation for much organic chemistry.
