Magnetic flux \(\mathit{\Phi}\) through a cross-sectional area \(A\) is defined as the scalar product between the magnetic flux density \(\class{violet}{\boldsymbol{B}}\) and the surface normal vector \(\boldsymbol{A}\). The surface normal vector \(\boldsymbol{A}\) and \(\class{violet}{\boldsymbol{B}}\) field vector enclose an angle \(\varphi\).
