In my physics class, we are learning about magnetic fields. One of the most interesting things I find about magnets is the inability to separate north and south poles, unlike the ability to separate positive and negative charges. No matter how small you go, even down to the atom, a magnetized object will always have a magnetic north pole and a magnetic south pole. For example, if you cut a bar magnet with a north and south magnetic pole in half, the two halves would both then form a north and south pole. Scientists have never observed a magnetic monopole, which is a particle that has just one magnetic pole whether that be north or south; however, scientists don't know why this is the case and are trying to figure out why this happens if a magnetic monopole cannot be observed.
