The main difference between physical characteristic magnet magnetic circuit and the circuit

by:Newland     2020-04-24
The major difference between electromagnet magnetic circuit and the circuit physical properties ( 1) Has the good conductive material, nature also exists to the current of the insulation material. For example, the resistivity of copper and 1. 69× 10 - 2 qmm2 / m, and rubber resistivity is about the ten double. But until now, still did not find the flux of the insulation material. Permeability of the smallest bismuth, its permeability is 0. 99982μ 。 The air permeability of 1. 000038μ 。 So we can see air permeability of the lowest material. Magnetic conductivity ferromagnetic materials are one of the best six of relative permeability is about 10 square. ( 2) Current is actually charged particles in the flow of the conductors, as a result of the existence of conductor resistance, electric work of electrically charged particles and energy consumption, the power loss is converted into heat energy. And magnetic flux does not represent any particle movement, also do not represent power is lost, so the analogy is a postscript to the feet. Circuit and magnetic circuit are further apart, each have their own don't ask, don't kiss principle in bales. Losses, so the analogy is lame. Circuit and magnetic circuit are further apart, each have their own don't ask, don't physical meaning. Professional term that is to say, less powerful magnet magnetic path. Therefore under the distance will be higher than ordinary magnet provided by suction strong magnet. 30 cm for single magnet, both powerful and common, is unable to induction enough suction. Of course enough magnetic block configuration can achieve this effect. Is refers to the conventional ferrite or other materials. In fact, powerful magnets compared with ordinary magnet, its characteristic is a big table, the ratio is about 4 times the left and right sides. Another characteristic is a high gradient. Gradient magnetic field changes on behalf of the unit length, table field to infinity, for example, the more quickly, the magnetic field strength of the higher gradient, on the other hand, a strong magnet magnetic field change with distance is bigger.
