Magnetic Flux

#Physics

$\displaystyle \Phi_{B}=\vec{B}\cdot \vec{A}=BA\cos \theta$

• $\displaystyle \vec{B}$ is the magnetic field passing through a surface
• $\displaystyle \vec{A}$ is a vector of the same magnitude as the surface's area and normal to the surface
• $\displaystyle \theta$ is the angle between $\displaystyle \vec{B}$ and $\displaystyle \vec{A}$
