What is flux linkage and how is it calculated for a coil with N turns in a magnetic field?.
Model answer
What a good answer should say
- Flux linkage (Ψ) is defined as the product of the magnetic flux (Φ) through one turn of the coil and the number of turns (N) in the coil, expressed as Ψ = N × Φ.
- It is calculated by multiplying the magnetic flux through a single loop by the number of loops in the coil.
Explanation
Why this works
This answer is strong as it clearly defines flux linkage and provides the formula for its calculation, demonstrating the relationship between magnetic flux and the number of turns in a coil. The question assesses the student's understanding of how magnetic properties relate to coil configurations.
