Note-A-Rific: Maxwell James Clerk Maxwell was born in Scotland in 1831, died in 1879. During his (short) lifetime he advanced the work of people like Ampere, Oersted, and Faraday to a point which allows us to enjoy the benefits of wireless communication (radio, T.V., cell phones, etc.) o Oersted had found that an electric current in a wire produces a magnetic field. o Faraday found that a changing magnetic field will induce a current. o Maxwell took it one step further… he said “Forget about the wires!” His theory was that even without wires… 1. A changing electric field will generate a changing magnetic field . 2. That changing magnetic field will generate a new changing electric field . 3. The new changing electric field will generate another magnetic field And so on… forever! This was Maxwell’s theory, but he knew that it would be very difficult to prove. Much of what he ended up doing involved a lot of heavy calculus (which we don’t study). He showed that once you have started up one of these waves it would continue on
