[amp_mcq option1=”Flux density” option2=”Reluctance” option3=”Ampere turns” option4=”Resistance” correct=”option2″]
The correct answer is B. Reluctance.
Permeance is the ability of a material to allow magnetic flux to pass through it. It is the reciprocal of reluctance, which is the resistance of a material to the passage of magnetic flux.
The other options are not correct because they are not related to magnetic flux.
- Flux density is the amount of magnetic flux per unit area.
- Ampere turns is the product of the number of amperes and the number of turns in a coil.
- Resistance is the opposition to the flow of electric current.
