What is the formula for calculating magnetic flux linkage in a coil?.
- A.Φ = B × A × N
- B.Φ = B × A
- C.Φ = N × I
- D.Φ = B × I
Model answer
What a good answer should say
- Φ = B × A × N
Explanation
Why this works
Magnetic flux linkage (Φ) in a coil is calculated using the formula Φ = B × A × N, where B is the magnetic flux density, A is the area of the coil, and N is the number of turns in the coil. This relationship shows how the total magnetic flux is affected by the number of turns.
