New Physics Video Playlist - Maxwell's Equations, Electromagnetic Waves, Displacement Current, & Poynting Vector - Physics

This physics video tutorial provides a basic introduction into maxwell's equations and electromagnetic waves. Maxwell's 4 equations include gauss' law for electric fields and magnetic fields, Ampere's law for magnetic fields, and Faraday's Law for electric fields. The basic idea is that a magnetic field can be produced from a changing electric field and a changing magnetic field can induce an electric field. This video explains how to calculate the displacement current between the plates of a parallel capacitor using the permittivity of free space and the rate at which the electric flux inside a capacitor changes. The electric flux is the product of the electric field and the area. The displacement current is also equal to the capacitance multiplied by the rate at which the voltage across the capacitor is changing. This video contains practice problems on electromagnetic waves which consist of electric fields and magnetic fields. The electric field is equal to the magnetic field multiplied by the speed of light. This video also describes how to calculate the magnitude of the poynting vector labeled S which has the units of intensity in w/m^2. S represents the energy transfer per unit area per unit time. This video explains how to calculate how much energy can be transferred from electromagnetic radiation. It also explains how to calculate the energy density of electric fields and the energy density of magnetic fields. This video on electromagnetic waves contain plenty of examples and practice problems.
