Motors and Generators A magnet, with lines of force around it, can induce a current. Generators use this effect to create nearly all our electricity. The Earth is a good example of a planetary dipole, where the lines of force point in a direction out of the South Pole and into the North Pole. Not every planet has a magnetic field. Venus is a rocky planet with no magnetic field.
Natural magnets have north and south poles.
Like poles repel and opposite poles attract. Magnetic field lines flow from north to south. D.M. Candelora, Copyright 1996, 1997.
