🔍 Key Concepts

• Inductance and air gaps in magnetic cores (how an air gap affects inductance) • Core saturation with DC current and its effect on the AC component in a choke • Difference between increasing vs decreasing inductance and saturation in a filter choke

💭 Think About

• Think about what happens to a magnetic core when you add an air gap: does it make the core saturate more easily or less easily with DC? • If DC saturation is reduced, what happens to the behavior of the coil for superimposed AC – does its effective inductance for AC go up or down? • Compare each statement: is it consistent with the typical purpose of adding an air gap to a choke used in a DC power filter?

✅ Before You Answer

• Verify whether an air gap increases or decreases core saturation tendency under DC bias • Check whether an air gap increases or decreases the effective inductance for the AC component in a filter choke • Confirm if the statement "inductance of the coil in general's decreased" is fully correct in the context of DC plus AC operation, or if it’s oversimplified/misleading
