Electromagnetic Field: Maxwell's Equations
We have already learned something about electrostatics and magnetostatics. However these laws and formulas and equations are kind of complicated and messy. Real truths should not be something like th

Electromagnetic Field: Magnetostatics
We have already learned something about electrostatics last times. Now we turn to focus on magnetostatics. In history, for some reasons, although magnets and magnetism were known earlier, the study o
Electromagnetic Field: Electrostatics
What are we trying to figure out when we talk about a force field? What are the force lines look like? Diverging or twisting? How can we measure them? What would happen if two fields connected toget
