     How do Magnets work? The underlying aspects of magnetism consist of the science of magnetic fields. Magnets have magnetic fields that push and pull objects toward and way from them. When an electron moves it generates a magnetic field with two poles north, and south respectively. Science cannot explain why this happens yet, it's just a factor of the universe that exists. However, we do know that opposites attract. The north pole attracts the south pole, and two of the same poles will resist each other.
