Magnetic Monopoles??
why do such things exist?? how exactly do they work? when cutting a bar magnet into half, both halfs have their own north and south pole right??
found this excerpt on the internet(i'm currently learning magnetism )If you've ever seen a compass, you will remember that it has the interesting property of always pointing to the north. This is because there is a magnet on the end of the compass needle. If you bring a bar magnet near to a compass, you will notice that the needle repels from the bar magnet's north pole. (my question is, how do we even know which pole is the north pole of the magnet?)This means that the compass needle is also a north pole. Like charges repel. So if the magnet is north, it should point AWAY from the north pole of the earth, since like charges repel. The answer to this little riddle is simple- the north pole of the Earth is actually a magnetic south pole. (another question: why must it be this way? why can't the south pole of the Earth be the magnetic north pole?)
