Electrodynamics

Learn about the electromagnetic properties of our universe, for example about electric charges, currents, electromagnetic fields and so on.

Lesson

Electromagnetic wave and its E-field and B-field components

Here you will learnthe wave equations for the E-field and B-field of an electromagnetic wave and how it can be simplified to a plane wave.

E-field change generates B-field
