The unnatural behaviour of a piece of iron in the proximity of a magnet never ceases to astound an audience even after repeated viewing. The effect called the magnetic effect seems magical and amazing. This relationship between a piece of iron and a piece of magnet chart a long span of time of over several centuries.
The use of magnets in mechanical and industrial applications is quite common in today's time. Magnets act as the fundamental driving force for electric motors and electric generators of various kinds. Every electric motor is equipped with magnets where the electrical coils are found surrounding the magnet. Electro-magnets are extensively used in telephones, telegraphs, door bells, cell phones, computers, tape recorders and so forth. Cranes are often equipped with electromagnets to pick up and drop heavy loads. Even industrial conveyor systems are fitted with electromagnets to separate metal parts from various materials. Truck mounted magnets assist in cleaning up construction sites.
In the current times of technological revolution, magnetic technology has helped in the development of the MAGLEV (magnetically levitated train). This system consists of a train track in a single rail system with the train levitating above the track. This technique almost eliminates all friction and reduces wear and tear on the train and the track. The train is driven by fluctuating electrical currents with the provision of high speed owing to negligible chances of friction. This technique though developed in theory will soon be done practically with the construction of the first MAGLEV train between Las Vegas, Nevada and Disneyland in California.
The need for greater efficient energy and superior methods of transportation has increased the importance of magnet technology. Mankind's discovery of the effects of magnetism and its numerous properties and uses is often times counted as one of our paramount achievements as par with the invention of the wheel and creating fire.
