Maggiore è la permeabilità del magnetico induttore ad anello, the lower the temperature it can withstand. If the inductance of the magnetic induttore ad anello is very high, the number of winding coils of the inductor can be reduced, and the large wire diameter copper wire winding system can be used.
Choose the appropriate magnetic core according to your own needs, but the core selection principle of magnetic induttore ad anello is generally unchanged, there are the following points.

1. La dimensione del anello magnetico deve essere completo e liscio, senza alcuna sporgenza, e più lungo è, meglio è.
2. Più l'apertura del nucleo magnetico è vicina al passaggio del cavo, meglio è.

3. Nella banda a bassa frequenza si consigliano 2-3 giri. Nella banda ad alta frequenza non sono consentite rotazioni.
What is the relationship between the color of a anello magnetico and its material?
Most of the anello magneticos need to be painted to facilitate the difference. Generally, iron powder core is distinguished by two colors, commonly used are red/transparent, yellow/red, green/red, green/blue and yellow/white, manganese core ring is generally painted green, iron silicon aluminum is generally all black and so on.
In fact, the color of the anello magnetico after firing has no inevitable relationship with the coating dyeing after spraying, but it is just an agreement in the industry.
For example, green represents a high-permeability anello magnetico;
The double color represents the iron powder core anello magnetico;
Black represents iron silicon aluminum anello magnetico and so on.
