- "Faraday took it to the next level. He invented the electric motor in 1821 and discovered electromagnetic induction in 1831. This led to the creation of the first dynamo, which was basically an early electric generator."
- "Faraday discovered that moving a magnet through a coil of wire produces an electric current, which led to the development of modern electric generators."

- "In the 1860s, Maxwell discovered that electric and magnetic fields oscillate together to create electromagnetic waves, which travel through space at the speed of light."
- "And here’s where Maxwell comes in. He figured out that electricity and magnetism are two parts of the same force—electromagnetic waves. He unified everything into his famous Maxwell’s equations."
- "Maxwell proved that light itself is an electromagnetic wave, connecting electricity, magnetism, and light."

- "In 1887, Hertz confirmed Maxwell’s theory by producing and detecting electromagnetic waves, which paved the way for modern wireless communication. Thanks to Hertz, we have radios, TVs, and Wi-Fi!
- "Finally, Heinrich Hertz proved the existence of electromagnetic waves! He generated radio waves and detected them using a coil and spark gap."
