Magnetic flux:

$\overline{){{\mathbf{\varphi }}}_{{\mathbf{B}}}{\mathbf{=}}{\mathbf{B}}{\mathbf{·}}{\mathbf{A}}{\mathbf{·}}{\mathbf{c}}{\mathbf{o}}{\mathbf{s}}{\mathbf{\theta }}}$

Part A

Area abcd = 0.4 × 0.3 = 0.12 m2

The z-axis and normal to area abcd are perpendicular.

ϕB = BAcosθ = (0.128)(0.12)(cos90°) = 0 Wb
