A set of 4 equations that describe Electromagnetism - in this video, I'll be covering just one of them. Because otherwise, I wouldn't be able to do it justice.

Don't worry, you don't need to know anything more than high school mathematics and physics in order to understand this video (assuming I've explained things correctly lol).

Hey everyone, I'm back from a fairly long break with a video on Maxwell's Equations! I asked you guys on Instagram a couple of weeks ago whether you wanted to see a video on Maxwell's Equations or whether you wanted a video on the model of the atom. Maxwell's Equations won out, so here we are.

Thank you so much if you voted in my poll, and if you don't already then follow me on Instagram (and Twitter) @parthvlogs

So, the Maxwell Equation I'm covering in this video states that the Divergence of a Magnetic Field is equal to Zero. In order to explain what this means and what it implies, I realised I had to describe what "divergence" meant, and in order to do that I had to describe what vector fields are.

So that's exactly what I've done. Firstly, we discuss vector fields and a few examples of vector fields, and then we discuss how to find the divergence of a vector field in a fairly intuitive and visual way (without going too much into the mathematical gore). Finally, we go on to looking at what this particular Maxwell Equation says about magnetic fields, and the implications of this - that there is no such thing as a magnetic monopole (single pole), and that there are no sources or sinks of magnetic field. This is why any magnet will always have a north AND a south pole - even when we cut a magnet into half, we get two smaller magnets which each have two poles. Thus, no evidence of a magnetic monopole exists to this day.

This video goes into quite a lot of detail, so if there's anything that isn't quite clear enough, then feel free to let me know in the comments.

Finally, thanks so much for watching. Feel free to drop this video a like, and subscribe to my channel if you haven't already. Hit that bell button if you want to be notified every time I upload - I make fun physics videos, though I don't have to try too hard because physics is already fun!
