How much flux is there in a magnetic field when its flux density is 5000 T and its cross-sectional area is 300 mm2?

The flux through a coil is given by
$\Phi = BA cos \theta$
where B= magnetic flux density
A= area of the coil
$\theta$= angle between B and normal to A
Since the angle is not given in the question, we assume magnetic field/ flux density to be perpendicular to the area.
therefore,
$\Phi$ = 5000*.0003 Wb
= 1.5 Wb
