Most people know the importance of electricity and electronics in modern life, but if you ask them about magnetism they might only be able to think of refrigerator magnets. In a short essay directed at a general, non-scientific audience, describe the importance of magnetism's interdependence with electricity. Pick at least two examples where the interrelationship between electricity and magnetism results in a useful product or technology and then explain how this interrelationship makes the product work.

Be careful to describe any important terms or concepts that might not be familiar to a general, non-scientific audience. For example, you may assume that readers probably lack an accurate concept of electric and magnetic fields.
