It is about the scientists with their contributions on the discoveries of electricity ang magnetism and the development of Electromagnetic wave theory.
AAHH!!
Hello! sorry if we surprised you ,we suddenly appear when you open the book.
By the way, I am James Clerk Maxwelll who contributed in developing equations that showed the relationship of electricity and magnetism. I noticed that electrical field and magnetic field can couple together to form electromagnetic waves.
Hello! Nice to see you, my name is Heinrich Hertz, I showed experimental evidence of electromagnetic waves and their link to light, and I proved the existence of radio waves in the late 1880s.
I demonstrate the magnetic effect based on the direction of current. Andre-Marie Ampere by the way, NIce to meet you!.
Why so serious kid? Michael Faraday, formulated the principle behind electromagnetic induction. It is a seminal breakthrough which laid the groundwork for later researchers such as James Clerk Maxwell, and led to important inventions such as electric motors, transformers, inductors , and generators.
My name is Hans, Hans Christian Oersted showed how current carrying wire behaves like a magnet.
Ow!, That's why this book has so many pages but it is empty.
