The basic considering of EPM
Multi media, various properties Magnetics, electronics, hydrodynamics,
material science, metallurgy, etc. .The process complicated, almost not vi
sible The numerical technology is the suitabl
e tool to study the EPM

The work of my group
From 1995, began to study EMS with FEM
From 1998, EMS and Secondary cooling study together
From 2000, EMBr, flowing-EM coupledFrom 2002, water treating with EM

The application in water treating
Two way to treat the water Treated with permanent magnet material:
study the effect of treating time; inspecting items: cloudiness , PH, conductivity and COD,
B0=1.3T
Alternative treating:
study the effect of treating time; inspecting items: cloudiness , PH, conductivity and COD
B=550Gs, frequency=5Hz

A compendious summary The Instantaneous values of field variables i
n EPM are very important in mastering the nature of EPM.
Media properties and its distributing influence on the magnetic field, induced current and Lorentz force.
The EM has great effect on water treating, especially using the alternative magnetic fields.
