The second sentence:

"although electricity be present even in materials that do not conduct charges well, such as glass or rubber, magnetism can only exist where charges are moving."

Why: it explicitly contrasts electricity and magnetism (using "although") and states a clear difference in conditions where each occurs. (Sentence 3 also compares the two, but 2 gives a stronger contrast.)
