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

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

(c) Calculate the magnetic flux that passes through the floor.
3 A house has a floor area of 120 m2 and an outside wall that has an area of 27 m2. The earth's magnetic field here has a horizontal component of 3.10 times 10-5 T that points due north and a vertical component of 4.50 times 10-5 T that points straight down, toward the earth. Determine the magnetic flux through the wall if the wall faces north. Wb Determine the magnetic flux through the wall if the wall faces east. Wb Calculate the magnetic flux that passes through the floor.

Explanation / Answer

a)

flux =BA

flux =27*3.1*10^-5

flux =8.37*10^-4 Wb

b)

flux =27*4.5*10^-5

flux =1.215*10^-3 Wb

c)

flux =0 Wb
