The drawing shows two surfaces that have the same area. A uniform magnetic field B fills the space occupied by these surfaces and is oriented parallel to the yz plane as shown. If = 17°, find the ratio xz/ xy of the magnetic fluxes that pass through the surfaces.

Answer 1

I have no idea of the picture. Flux is B.Area, where . means dot product.

Answer 2

90-17=73
(cos73)/(cos17)
