【Abstract】 The air purification technique of electrostatic removal of particle in electromagnetic field is presented novelly by authors.Starting from the electric drift theory of charged particles, it is explained that the theoretical base of purification efficiency can be increased more distinctly by applying parallel magnetic field than by applying perpendicular magnetic field. Based on further experiments, it is presented that there is an optimal initial velocity of charged particles to reach higher purification efficiency. It is explained on base of the electric drift theory of charged particles that the purification efficiency is lower by applying perpendicular magnetic field than without applying magnetic field under the special distances between collecting plates so as to perfect this new technique.更多还原
