Reluctance of a ferromagnetic material is for a conductor to the:
Correct answer: A. Resistance
- A. Resistance
- B. Conductance
- C. Inductance
- D. Capacitance
Explanation
The reluctance of a ferromagnetic material is similar to the resistance of a conductor. Just as resistance opposes the flow of electric current in a conductor, reluctance opposes the flow of magnetic flux in a ferromagnetic material. It's like a resistance to the magnetic field.

About Magnetic Flux
Magnetic flux measures the magnetic field passing through a surface, calculated for a uniform field as Φ = BA cos θ, where θ is the angle between the field and the surface normal. Questions involve area, field strength and orientation, the weber as its unit, and the distinction between flux and magnetic field.
