I would like to express my special thanks of gratitude to my teacher, Mrs. Sandhya ma’am, who gave me the golden opportunity to do this wonderful project on the topic of adsorption. This has helped me in doing a lot of research, and I came to learn about so many new things. I am really thankful to her.
Secondly I would also like to thank my parents and friends, who helped me a lot in finishing this project within the limited time. I completed this project not only for marks, but to also increase my knowledge.
Thanks again to all who helped me.
Electromagnetic induction is the production of a potential difference (voltage) across a conductor when it is exposed to a varying magnetic field. It underlies the operation of generators, transformers, induction motors, electric motors, synchronous motors, and solenoids.
Michael Faraday is generally credited with the discovery of induction in 1831 though it may have been anticipated by the work of Francesco Zantedeschi in 1829. Around 1830 to 1832, Joseph Henry made a similar discovery, but did not publish his findings until later.
An easy way to create a magnetic field of changing intensity is to move a permanent magnet next to a wire or coil of wire. Remember: the magnetic field must increase or decrease in intensity perpendicular to the wire (so that the lines of flux "cut across" the conductor), or else no voltage will be induced:
Faraday was able to mathematically relate the rate of change of the magnetic field flux with induced voltage (note the use of a lower-case letter "e" for voltage. This refers to... [continues]
