How far is it, I will roll how far circular permanent magnet
Large circular permanent magnet knowledge popularization, waiting for? Miss this time, penitence lifetime, circular permanent magnet what expression of magnet, fast with the Shanghai YingGui magnetic industry co., LTD. Small make up together and see it!
We are among the basic theory of electromagnetism, we will often in electromagnet related study, experiment and communication applications encountered the following issues to be discussed.
Size of the magnetic magnet and what factors are related?
First we have to understand that is what is the electromagnet, the so-called electromagnet is a core with the basic structure of the coil winding, so when the coil when the current; It can produce a kind of electromagnetic devices. So what it is about the size of magnetic force produced by the specific and what factors are related?
First: solenoid magnetic round the coil size and number of turns is related, in general, the electromagnet coil number of turns, the more it shows that through the current, the greater the result, magnet magnetic will be stronger.
Second: and core materials and permeability is related to.
Third: and the electromagnet, the current in general, the higher where it into the current of the magnetic force will be higher. Fourth: magnetic and electromagnet core cross-sectional area is also related, such as length and thickness.
May arise, of course, in addition to the above several factors, and other factors, including the type of power supply, the stand or fall of enameled wire, iron core of the shape of materials, and coil connection and so on all has to be considered, so specific about the size of magnet magnetic and what factors are concerned, this requires us to do experiments, practice will come to the conclusion that better!
