A house has a floor area of 110m 2 and an outside wall that has an area of 27 m

Question

A house has a floor area of 110m2 and an outside wall that has an area of 27 m2. The earth's magnetic field herehas a horizontal component of 2.90 x 10-5 T thatpoints due north and a vertical component of 3.50 x 10-5 T thatpoints straight down, toward the earth. (a) Determine the magnetic flux through thewall if the wall faces north.
1 Wb

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

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

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

Explanation / Answer

a) for a wall facing north the complete B horizontal will passthrough it thus = B.A = 27*2.9*10^-5 = 7.83 *10^-4 weber b) for a east facing wall as thickness of wall is assumed to be0 = 0 c) for the floor = 110*3.5*10^-5 = 0.0039 weber
