Then the analysis and experimental study are made about three possible factors to affect the hysteresis of the actuator sys- tem, such as the magnetoconductivity of yoke、the stiffness of spring and the change rate of magnetic density, the ways in effect which minishe.

Discussion on magnetic induction and magnetic field strength;

Based on the expression of the damping force,the effect the gap,length,radius,magnetic field strength and velocity of piston on damping force is analyzed.

Controlled slowdown of equivalent light speed and its applications in measuring magnetic field intensity;

On the role of magnetic field intensity effects on the discharge characteristics of Hall thrusters

The results showed that in specifically range the variety of electric current intensity and frequency remarkably affect the magnitude of magnetic field intensity.

The magnetic field gradient of these magnetic field profiles is obtained quantitatively by using Lorentz fit.

Four single component magnetic field sensors are used to make up of a detection device that has dual-magnetic field gradient inputs as reference.

The results show that the product of magnetic flux density and magnetic field gradient should be very large to get good oxygen enrichment results, which is difficult to realize.
