                                                   Magnets Facts

Magnets are somewhat strange and interesting materials that can be made in any shape and size. They attract certain types of metals like iron, cobalt, nickel. Any magnet has the magnetic North Pole and the magnetic South Pole. If the same poles of two magnets are placed near each other then they will repel and if opposite poles are placed near each other then they will attract. Even our planet earth acts like one big bar magnet. It also has a magnetic north and magnetic south. The earth’s core is believed to be a mix of iron and nickel that gives it its own magnetic field.
