Dear student,
It was the use of magnets in the engineering field, which paved way for  its extension to the biological and medical fields. It began with a  chance discovery when the Russian scientists were confronted with a  peculiar and insolvable engineering problem. The boiler feed water pipes  carrying the water and the automobile radiators slowly got clogged with  the dissolved salts. This resulted in the reduction of their thermal  efficiency. In order to increase the lumen of the pipes and the capacity  of the radiators, these salts had to be scrubbed off periodically.  
 
 The added workload and increased operational cost towards extra  consumption of the fuel and lubricants became a matter of concern.  Similar problem was confronted by the oil industry, which helplessly  watched the deposits of salts in the oil pipes. In order to reach a  solution, successful experiments were conducted where; the magnets were  employed for dissolution of Salts. Almost instinctively, they placed the  pipes and the radiators in strong magnetic fields. The reverse process  of dissolution of the salts began, which considerably narrowed their  burden.
						

							
Magneto-hydrodynamics is what happens when water passes through a properly focused magnetic field. The magnet field breaks up some of the complexes that are carried in the water, freeing the captive mineral particles. Once free, these particles act as crystallization centers, giving the surrounding mineral molecules in the water something to “stick” to, rather than forming new layers of scale on the inside of plumbing and appliance surfaces. As these crystallization centers attract mineral molecules, they form circular platelets, which remain in the water rather than attaching themselves to surfaces and causing scale build-up.
Even back then, when the magnets were far weaker than they are today, the effects were remarkable. The treated water behaved as if it were “softer”, with less mineral content, and scale build-up was significantly reduced. Magnetic fluid conditioning caught on first in the eastern world, where other water softening methods and equipment were not commonly available. Highly favorable reports soon began filtering back from Chins, Russia, P oland, Bulgaria, and other eastern countries agricultural, commercial, and industrial use. In the developed countries of the western world, where chemical and other water softening systems were well entrenched, magnetic fluid conditioning took longer to gain acceptance. But its benefits were too dramatic to remain obscure for long. Systematic research from respected institutions began to be conducted, quantitive methods were developed to evaluate the effectiveness of magnetic water conditioning devices, and the findings revealed overwhelmingly positive effects.
