When using an inductive coil, the first step is to check whether the inductance meets the requirements. This can be done using an inductance tester, which can not only measure the inductance, but also measure the Q value of the coil.When a short circuit occurs in the coil, it will greatly increase t Read More »

Inductance can be made by winding a conductive material around a magnetic core, such as copper wire, or by removing the magnetic core or replacing it with ferromagnetic material. Core materials with higher magnetic permeability than air can more tightly confine the magnetic field around the inductiv Read More »
