Professor Vale showed us Faraday’s Law by using a giant coil to generate energy. The coil worked in the same way the as tube used in our lab by generating mass amounts of voltage. By placing a stick with a metal pole coming of the top of it just near the top of the coil generated a mass amount of energy and a electric current was visable. Professor Vale also explained the history of Nikola Tesla who developed the technology that was on display along with many other advancements that we take for granted in our daily lives.
