Abstract: Based on theories of chemistry, physics, electromagnetism, phase separation, and so_ lid particle settlement in the paper a mechanism of wax protection by intensive magnetism was discussed. It is assumed that aggregation and settlement of wax molecules are hampered by the clockwise polarization and partial magnetism of wax molecules due to action of intensive magnetic field. An application and test on gathering pipelines in oil fields are, introduced, and the factors to affect wax protection are also analysed.
