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.

This paper points out the deficiencies of the diesel rock drill’s ignition system,such as the flywheel demagnetizes and the field strength is low when it is magnetized-thus,the flashover of spark plug is not enough strong,diesel rock drill’s starting is in difficulty and so on,then gives a method to improve the flywheel's instructure and the performance of the engine start is improved obviously.

Differences in degree of the influence of shape and weight of Ni-Cr alloy and different field strength on MRI artifact was compared.

To compare the relationship between the artifact of different fixed prosthesis and field strength,scanning sequence.

Physical sense of H magnetic intensity and use;

5 g/cm3 display diamagnetism;the magnetic susceptibility of low density coal reduce along with the magnetic intensity increase,but the diamagnetism increase;the paramagnetic of high density coal decrea.

The experimental results indicate that no matter what direction the sample placed to,the laws of the distributing of the magnetic intensity do not change.
