A magnet has two poles – north and south. If you cut a magnet in half, each piece will also have two poles: north and south. To bring the poles closer together and make the magnet attract more strongly to metal, it's bent into a horseshoe shape. In permanent magnets, the north pole is usually painted blue, and the south pole is painted red.
And we're also flying through space on a giant magnet, which is why a compass works. Its needle is attracted to Earth's poles. Though opposite poles attract, so it turns out that the magnetic north pole is located in the south.
And drawing it is simple. Start with the letter U. Divide it with a line in the middle. Add volume and color.
