Magnetic flux $\mathrm{桅}$seems to be the magnitude of magnetic field which passes through some kind of ring of area $A$. If the magnetic field lies straight towards the plane's normal, This magnetic flux was provided by

localid="1648909787313" ${\mathrm{桅}}_m=BA$ $\left(1\right)$

The magnetic flux, however, would be supplied by if the magnetic field forms an angular position only with planes.

${\mathrm{桅}}_m=BA\cos 鈦�胃$ $\left(2\right)$

Here $B$denotes the magnetic field as well as $A$denotes the substring circumference. Two fields exist, each of which has different scales and inclinations. The square consists of 2 rectangle rings of the same area and tilted points being bent at ${90}^{鈭�}$. As a result, the bent square's overall flux was

${\mathrm{桅}}_{\text{net}}=2BA\cos 鈦�胃$ $\left(3\right)$

Single rectangle's surface area is

$A=\left(0.10\mathrm{m}\right)\left(0.05\mathrm{m}\right)=5脳{10}^{鈭�3}{\mathrm{m}}^2$

Then, we enter the data for $A$, $胃$and $B$into equation $\left(3\right)$to get ${\mathrm{桅}}_{\text{net}}$

${\mathrm{桅}}_{\text{net}}=2BA\cos 鈦�胃$

$=2\left(0.050\mathrm{T}\right)\left(5脳{10}^{鈭�3}{\mathrm{m}}^2\right)\cos 鈦�\left({45}^{鈭�}\right)$

$=3.5脳{10}^{鈭�4}\mathrm{T}鈰�{\mathrm{m}}^2$
