... poles. If you cut these halves into two more pieces, each of the new magnets will also have two poles. And so on. You can never slice a magnet in half and get only one pole. One of the interesting questions that modern physicists play around with is whether a magnet with a single pole can exist. Suc ...

The Electric Field due to a Point Charge
... Examples of electric insulators are paper, chalk, rubber, plastic, and air. We will see later, however, that there are certain conditions that cause electric insulators to “break down” and become electric conductors. In an electric conductor charge moves freely. When the conductor is in electrostati ...
