Electromagnetism (electric and magnetic phenomena) 1. Electric charge 1a. Qualitative description I. Electrostatics This is about: electric charges, electromagnetic forces, and electromagnetic fields This is about: non-moving electric charges, electrostatic forces, and electrostatic fields. (With very good approximation, electrostatics could be applied to slow moving charges. Slow means that the speed of the considered charge is much smaller then speed of light: v<<c) There are two and only two types of electric charges Charges of the same type repel, and charges of different type attract (this is already qualitative description of electrostatic forces) These two types are referred to as positive and negative (+q and –q)
