Science Chapter 4 Electricity and Magnetism. An object that does NOT conduct electricity… insulator. Electric charges move in a looped path called a circuit – starts and ends in the SAME spot A simple circuit contains a source of energy and at least. Electricity& Magnetism It’s ...
Diamagnetism All materials are diamagnetic in nature. Diamagnetism is a very weak form of magnetism, exhibited only in the presence of a very strong external magnetic field. It is difficult to observe in everyday life. Materials like ferromagnetic materials have magnetic properties that overshadow the...

Charging by “INDUCTION”…OR CONTACT! This is how balloons stick to walls… Why do you rub the balloon first on your head? *to “pull” electrons off your hair, and on to the balloon *the balloon now has more electrons than it should, causing it to become negative, while everything ...
