Magnetic flux
Φ = BA cos θ
Where: A = area (m²) / amplitude, B = magnetic field (T), Φ = magnetic flux (Wb), θ = angle
Solved example
Given: A = 7, B = 5, theta = 60°
Find: Phi (magnetic flux (Wb))
- Formula: Φ = A·B·cos(θ)
- Substitute the values: Φ = 5·7·cos(60°)
- Result: Φ = 17.5 Wb
Answer: Phi = 17.5 Wb
