When did Michael Faraday discover electromagnetic induction, the principle behind the electric transformer and generator?

Correct option is D

The correct answer is (D) 1831.

Explanation:

• Michael Faraday discovered electromagnetic induction in 1831, which is the fundamental principle behind devices such as the electric transformer and generator.
• His discovery demonstrated that a changing magnetic field can induce an electrical current in a conductor, laying the foundation for the development of electrical power generation.

Information Booster:

• Electromagnetic Induction:

  • The phenomenon of generating electric current through the motion of a conductor within a magnetic field.
  • Faraday's law of induction is the basis for the operation of transformers, electric motors, and generators.

• Michael Faraday:

  • A renowned English scientist who made groundbreaking contributions to the fields of electricity and magnetism.
  • Known for his work on electromagnetic fields, electricity, and the development of the electric motor.

• Faraday's Discovery:

  • In 1831, Faraday demonstrated that a current could be induced in a coil of wire by moving a magnet in and out of the coil, proving the principle of electromagnetic induction.
