What is the formula for calculating magnetic flux linkage in a coil?.
- A.Φ = B × A
- B.Φ = N × B × A
- C.Φ = I × R
- D.Φ = E × t
Model answer
What a good answer should say
- Φ = N × B × A
Explanation
Why this works
The formula for magnetic flux linkage (Φ) is given by the product of the number of turns in the coil (N), the magnetic flux density (B), and the area (A) of the coil. This relationship is essential in understanding how coils interact with magnetic fields.
