A History of Magnets And Their Many Uses part 2- magnetic ball bracelets

Today, the use of magnets in industrial and mechanical applications is quite common. (magnetic ball bracelets) Magnets are the basic driving force for all electric motors and electric generators. (magnetic ball bracelets) Every electric motor is dependent upon magnets with electrical coils surrounding the magnet. As the current moves, the magnet follows in sequence. (magnetic ball bracelets) Electro-magnets are used in telegraphs, telephones, computers, cell phones, door bells, tape recorders, etc. Electromagnets are used on cranes to pick up and drop heavy loads, as well as in industrial conveyor systems to pull metal parts out of various materials. Truck mounted magnets are also used to clean up construction sites and prevent nails in vehicle tires. (magnetic ball bracelets)

Magnet technology has also been used to develop the MAGLEV (magnetically levitated train). The train track is a single rail system with the train levitating above the track. (magnetic ball bracelets) This virtually eliminates all friction and wear on the train and the track. Fluctuating electrical currents drive the train, and because friction is not a factor, the trains can move at very high speeds. (magnetic ball bracelets) Theoretically, the speed could be infinite, if it were not for wind resistance on the train cars.
