What is magnetism?
Essential Question: Do objects have to touch to apply a force on each other?
Magnetic materials, including the Earth, have surrounding force fields that interact with magnetic objects around them. Magnetism is caused by the movement of electrons, which spin like tops. When all the electrons spin in the same direction, the object becomes magnetic.
