Magnetic Flux through a Surface
45°
ΦB = B × A × cos(θ) = 1 × 1 × cos(45°) = 0.71 Wb
This simulation shows the magnetic flux through a surface placed in a uniform magnetic field. Use the slider to change the angle between the magnetic field and the area vector. The flux changes according to the equation ΦB = B × A × cos(θ), where B and A are both taken as 1 unit for simplicity.
