Why do magnets attract or repel each other even when they are held apart?

Many things are magnetic, though in varying degrees, especially special rocks called magnets. Magma, lava underneath the surface of the earth, is highly magnetic, as lava often comes out in special areas on the surface forming a visible magnetic field. Humans are made from soil/dirt, and we have the same minerals in us as the earth does, and since the earth is magnetic, so are we, and scientists have proven that recently. They have found that we have ultramicroscopic minerals in our heads or in our brains that are magnetic, though they don't work the same way as the magnets in animals function. Animals navigate, especially during migration, due to the magnetic field of the earth, like a compass, and God designed them just for that. Also, you can make a makeshift compass by finding a small piece of light metal wire and rubbing it on your head to get static electricity. Now that it is magnetized, place it on a leaf in a pool of water, and it will align like a compass does! All thanks to Bear Grylls and his show of Man vs. Wild on Discovery channel!
