  • Details of leakage inductance.

    The magnetic field lines generated by the coil cannot all pass through the secondary coil, so the inductance that produces the leakage magnetic field is called leakage inductance. Refers to the part of the magnetic flux that is lost during the coupling process of the primary and secondary transfo...

  • Unit conversion of inductance

    Inductance is a closed loop and property of a physical quantity. When the coil passes current, a magnetic field induction is formed in the coil, which in turn generates an induced current to resist the current flowing through the coil. This interaction between current and coil is called inductanc...

  • What is the relationship between the color of the magnetic ring and the material?

    Most of the magnetic rings need to be painted to facilitate the distinction. Generally, the iron powder core is distinguished by two colors. The commonly used ones are red/transparent, yellow/red, green/red, green/blue and yellow/white. The manganese core ring is generally Painted green, iron-sil...
