A house has a floor area of 119 m2 and an outside wall that has an area of 32 m2. The earth's magnetic field here has a horizontal component of 2.1 x 10^-5 T that points due north and a vertical component of 5.0 x 10^-5 T that points straight down, toward the earth.

(a) Determine the magnetic flux through the wall if the wall faces north.
_________Wb

mag flux = BH A
mag flux = (2.1 x10^-5T)(32 m^2)
mag flux = 6.72 x 10^-4 Wb

(b) Determine the magnetic flux through the wall if the wall faces east.
_______ Wb

mag flux = BH A COS 90 degrees + Bv A cos 90 degrees

mag flux = 0 Wb

(c) Calculate the magnetic flux that passes through the floor.
_______ Wb

mag flux = Bh cos 90 degrees + BvA cos 0.0 degrees

mag flux = BvA

mag flux = (5.0 x 10^-5)(119 m^2)

mag flux = 5.95 x 10^-3 Wb
