Q. Why do wire and a compass work to detect electric currents?
A. I’m going to start off with the basics here. A compass points north. Everyone knows that. Why does it point north? Well, all magnets have two “poles” or ends. One end of the magnet is called the north-seeking pole. The north-seeking pole is often abbreviated to north pole or the letter N. The north pole end of a magnet is usually colored red. The other end of a magnet is called the south-seeking pole. The south-seeking pole is often abbreviated to south pole or the letter S. The south pole end of a magnet is usually colored blue. Have you ever heard of the phrase “Opposites attract”? That’s accurate with magnets too. Let’s say that you had two magnets and you put them right
