Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is 1831.
Key Points
- Michael Faraday discovered electromagnetic induction in the year 1831.
- This discovery is crucial as it laid the foundation for the development of electric transformers and generators.
- Faraday's experiment involved moving a magnet through a coil, which generated an electric current within the coil, demonstrating the principle of electromagnetic induction.
- His work on electromagnetic induction is considered one of the most significant contributions to the field of electromagnetism and electrical engineering.
Additional Information
- Electromagnetic Induction
- It is the production of voltage or electromotive force due to a change in the magnetic field.
- This phenomenon is the principle behind transformers, inductors, and many types of electrical generators.
- Michael Faraday
- He was an English scientist who contributed significantly to the study of electromagnetism and electrochemistry.
- Faraday's laws of electrolysis and his work on the Faraday effect are also notable contributions.
- Electric Generators
- Devices that convert mechanical energy into electrical energy using the principle of electromagnetic induction.
- Generators are widely used in power plants to produce electricity for homes and industries.
- Transformers
- Electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
- They are used to increase (step-up) or decrease (step-down) voltage levels in power transmission and distribution systems.
