LET THERE BE... Voltage? | Maxwell's Equation #2 Explained for Beginners

The second Maxwell Equation made simple!

Hey you lot, I'm back with possibly my longest physics video yet - hopefully it's digestible haha! A lot of you enjoyed my previous video on one of Maxwell's Equations of Electromagnetism (check it out here: https://www.youtube.com/watch?v=0jW74lrpeM0&t=502s ) and asked me to make a follow up. Therefore, here I am explaining another one of these equations (2 more to go!)

In this video, we're discussing the Maxwell Equation that links the contribution of an electric field around the perimeter of a surface to the rate of change of magnetic flux through that surface. In other words, this Maxwell equation is a very rigorous way of encoding the effects of electromagnetic induction. Some of you will be familiar with this concept, having learnt about how moving a magnet in and out of a coil of wire generates a voltage (or e.m.f.) across that wire. If the wire is a closed loop, this allows a current to pass through the wire.

Along the way, I explain all the symbols in this equation and what they mean. We briefly discuss the vector nature of electric and magnetic fields, as well as how these are relevant to the little vectors that we break up our surface, mentioned earlier, into. We also have a look at the meaning of the squiggly "S" symbols seen on either side of the equation - more commonly known as the integral symbols. Hopefully by the end of this video, you should be able to roughly understand what each symbol in the equation means, and how it relates to quantities that we can actually observe in real life and measure. As a young physics enthusiast, one thing I always found difficult was understanding these complicated equations and how they linked back to real life. How could this mathematics that looks so complicated (yet relatively simple considering it describes ALL of electromagnetism) be translated into a description of our reality? That's the question I'm trying to help answer here.

If there's anything that's unclear then do let me know in the comments and I'll try and clarify. Let me also know if I've made any errors!
