the molten iron core
Earth has a molten liquid core containing iron. It is believed that as it moves or spins, it creates an electric current that causes a magnetic field around the Earth. The field is believed to be created by this dynamo action. The magnetic field makes the Earth act like a huge magnet so it attracts like one. That's why it pulls the magnetized needle in a compass and makes it point in the general direction of the North Pole.>alryan< add me on facebook: alryanupi@yahoo.com
makes current flow through a magnet
There are a range of metals which can be used to make a magnet.
They move the ocean floor as if it were on a giant conveyor belt.

the molten iron core
The Earth's magnetic field is generated by the movement of molten iron in its outer core. This movement creates electric currents, which in turn generate a magnetic field around the planet. This magnetic field acts as a giant magnet, with one pole near the geographic North Pole and the other near the South Pole.
makes current flow through a magnet
I believe the earth's core creates friction as it the earth rotates and that generates the field. Not 100% on that though.
The compass needle is itself a magnet which is why it always points north according to the earth's magnetic field. If you place a magnet (Whose magnetic power is stronger than the earth's) close to the compass its needle will be attracted t the magnet and not to the North Pole.
Mars has giant mountains (i.e. Olympus Mons).
What Makes Someone a magnet to rabies is if an animal with rabies bites, licks, or attacks you.
The arrangement of molecules in a magnet makes itself a magnet.if u want to know further,try searching "Ewing's molecular theory of magnetism".
The refrigerator isn't actually a magnet, it it simply made of metal which magnets can then stick to.
