Electricity and magnetism are closely related: Power lines generate a magnetic field, rotating magnets in a generator produce electricity. However, the phenomenon is much more complicated: electrical and magnetic properties of certain materials are also coupled with each other. Electrical properties of some crystals can be influenced by magnetic fields--and vice versa. In this case one speaks of a "magnetoelectric effect." It plays an important technological role, for example in certain types of...
