Effect of StaticMagneticand Pulsated Electromagnetic Fields On the Dynamic and Kinematic Viscosity of Metal Cutting Fluids

Abstract

In this paper, authors investigated the difference between the influenceof staticmagnetic field and pulsating electromagnetic field on metal cutting fluids. Two essential physical parameters of the cutting fluids, dynamic and kinematic viscosity coefficients were analyzedduring the experiment in the same laboratory condition.The results obtained from the experimental researchshow thatthe influence of thestatic magnetic field onsample metal cutting fluids is greaterthanthe influence ofthe pulsating electromagnetic field.Such as, after magnetizing cutting fluids under the effect of three various static magnetic field strengths, the kinematic and dynamic viscosity havedecreased about 17%and 6% respectively,while they declined about 7% and 4% after magnetizing the fluidsunder the effect of the same electromagnetic magnetic field strengths. Moreover, special magnetizing devices have beendesigned to magnetize different types offluids intheirflowing condition.
