🔍 Key Concepts

• Inductance and permeability – how the magnetic properties of a core affect the inductance of a winding • Magnetic saturation – what happens to a core when the magnetic flux reaches a maximum usable value • Difference between inductance, reactance, and dielectric strength in magnetic/electrical components

💭 Think About

• Ask yourself: in a saturable-core device, what property of the core can be changed by a DC control current to influence the AC inductance of the load winding? • Which option refers to a magnetic property of the core itself, rather than an electrical property of the winding or insulation? • Think about what the word "saturable" is referring to in the name "saturable-core reactor"—what is being driven toward saturation?

✅ Before You Answer

• Make sure you understand that dielectric strength is related to insulation and electric fields, not magnetic cores • Recall that reactance is a result of inductance and frequency, not a direct physical property of the core material • Focus on the option that directly involves changing the magnetic operating state of the core material, which in turn affects inductance
