Circular powerful magnet magnetic strength related to what factors?
How long can round powerful magnet magnetic can last? So take this opportunity to Shanghai today YingGui magnetic industry co., LTD. Is really a detailed answer on this question, partners can listen carefully!
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. Solenoid magnetic strength 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 produces magnetic strength concrete and what factors are related?
First: the magnetic strength of the electromagnet coil number of turns is related, in general, the electromagnet coil number of turns, the more it shows that the greater the current through, thus, 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.
In addition to the above several factors, of course, when we are in the lab, there are other possible 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 what about the magnet magnetic strength and factors, this requires us to do more experiments, practice can better conclusions.
