The north pole of one magnet will repel and push away the north pole of another magnet. Every magnet is surrounded by an invisible, three-dimensional magnetic field. The strength of a magnet is stronger as you get closer to it, and likewise its strength is weaker as you are farther away. The force of magnetism, simply put, is due to the motion of electric charges.
More uses for magnets are found every day. Look through the gallery and see if you can spot the following: Floating reduces friction and allows the train to run more efficiently. Its magnetic field is like a bar magnet at its centre.
