Common carp (Cyprinus carpio) not only showed obvious magnetic biological effect but also had effect threshold when magnetized for 4～12 h with the magnetic flux density of 0 46～1 50 mT and 2 10～4 50 mT.

The magnetic flux density on the crack tip in a metal pipeline was studied by numerical simulation method.

In the design of transformer,The selection of maximum magnetic flux density B m is a complex problem.

Calculations and experiments are carried out on both magnetic flux density and eddy current loss of the non-magnetic steel plate and of the coil in this model.

It is a necessary to predict a magnetic flux density surrounding a current-carrying conductor in design of EMC and current sensor.

The Saccharomyces Cerevisiae and Escherichia Coli as the object microorganism, the effect of the magnetic flux density, the time of magnetic field pole conversion on the destruction rate of microorganism was probed.

The simulation result of the distribution of the magnetic lines of force,the magnetic-flux density as well as the coil response current curve and the pitch point magnetic field strength curve are obtained.

A method for calculating air-gap flux density was proposed and the maximum error was 6.

This paper first introduce several magnetic parameters of the ferrite core used for electronic ballast and their effect on the magnetic inductance,these parameters include working and saturated intensity of magnetic flux and magnetic conductivity,then measure the parameters of 3 kinds of magnetic cores at 100kHz with the biggest motivating current method.
