Magnetism - comparing its basic properties with the basic properties of electricity there are similarities, yet distinct differences, seen. Together, electricity and magnetism can be combined to form the more general theory of electromagnetism - seeing that electricity and magnetism can be seen as "opposites sides of the same coin." One topic that was seen for electricity was the special and common case of the electrostatic equilibrium of a conductor. Here several properties were given with the primary one that the electric field is zero inside a conductor in this state. This is such an important situation for it brings up the concept of "electric shielding", which is utilized in many places, from shielding circuits by placing them inside a metal box (a conductor) to protecting electrical devices inside a special plastic bag to nullifying cell phone signals, etc., inside cars of some transit systems.

With magnetism's connection to electricity, one may wonder if electric shielding has a magnetic counterpart? In brief, yes, but how does it work, and how does it compare/contrast with electric shielding? This is what you want to consider, look up, and discuss somewhat briefly, as well as give a real-world application.

Another very common and important concept seen is that of induction with many applications discussed, the two big ones being motors and generators, though, as seen, they are basically the same device working in opposite directions; transformers being another big app.

Here, find an application of induction, not discussed in the text, and briefly discuss it. Better, can you find an app. of induction in your field of study?
