  • It's time to go a little deeper with our understanding of classical physics! From the very introductory conceptual tutorials on electricity and magnetism, we need to apply some more rigor and use advanced math that will help us really understand these topics. To start we will examine Maxwell's equations. These are the gold standard for describing electromagnetic fields. If the math looks unfamiliar be sure to visit my mathematics playlist for some review. First up, Gauss's law for the electric field!

    I look forward in using some of this when I'm teaching Extra Class licensing for Amateur Radio. Some want to really know the physics and I'm not a good source as I'm rusty myself, and most communicators about RF design and and electrical fields on YT are way way older.

    Nice simple explanation! However, the topology of a monopole charge is a sphere, while the topology of a dipole charge is actually a torus shape. And also there are two fields simultaneously at play, the electric field and the dielectric field. The electric field is a transverse wave oscillation that manifests from the dielectric field impulse at each oscillation. The dielectric field in a dipole charge is a scalar and longitudinal impulse, and is shaped like two inverse cones that meet at the point of charge, while the electric field is a torus shape that surrounds that charge with the holes in the torus formed by the two inward facing cones of the dielectric field.

    Hi sir. Can you make a vid about Plasmons after Maxwell Equations? I don't fully understand this. Like how to prove that the EM wave will be reflected when the frequency of EM wave is less than the Plasma frequency of materials, by using Maxwell equation? How the metals have Electric Fields in plasma oscillations if metal's permittivity is infinite? thank you in advance.

    Question - if you have a square 1-ton block, and you have four magnets attached to the bottom side of this block. This block is centered on another block, balanced. If you had a platform on the ground underneath this balanced block and it had four opposing magnets positioned in a larger circumference from the block, could you lift the platform up, and by doing so, would lift up the 1-ton block. Would this weight be the same as if you just tried to lift the block up without magnets or would the opposing magnetic force lift the 1-ton block for you much easier? P.S. - I know very little about magnetism...

    The normal to a sphere is not constant (it is radially outwards) and varies at every point on the sphere. It is also a vector, so the explanation at 8:30 is incorrect, What you need to say is that vector E=E(r)n where E(r) is the magnitude of the electric field at radius r. Then E.n=E(r), which is independent of position on the sphere. Only then can you take it outside the integral.
