magnetic poles

The locations on a magnet at which lines of flux leave and enter. A freely suspended magnet points toward magnetic poles. One end of the magnet is north-seeking and labeled “N,” while the other end is south-seeking and labeled “S.” All magnets have both poles. Typically, the north and south poles are indicated in red and blue colors, respectively, in illustrations and are referred to as the red and blue poles.

"I suppose you always want what you've never had, and the Northern Lights hung in my mind as something I thought I would never see and yet, as I got older, longed to see with all my heart." The Northern Lights phenomenon occurs when particles carried on solar winds are attracted by the magnetic poles. As the particles hit the top of the atmosphere, their energy is converted into the world's most astonishing light show.
