Next: The Magnetic Field Up: Main physics index Previous: Magnetism


The movement of a compass needle towards the North Pole and the attraction of a fridge magnet to the refrigerator are two examples of magnetism in our everyday lives. In this chapter we will examine a magnetic field in detail and begin to explore the sources of magnetism. We will also begin to see a connection between magnetism and electricity which, when developed further, is at the heart of one of the most successful theories in physics.
