Part A Find the magnitude of the magnetic flux through the floor of a house that measures 20 m by 17 m. Assume that the Earth's magnetic field at the location of the house ha horizontal component of 3.0x10-5 T pointing north, and a downward vertical component of 4.8×10¯5 T. Express your answer using two significant figures. $= VE ΑΣΦ = ? Wb

Part C Is this value of magnetic field cause for worry? Yes. Since this field is much greater than the earth's magnetic field, it would be expected to have more effect than the earth's field. Yes. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. No. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. No. Since this field is much smaller than the earth's magnetic field, it would be expected to have less effect than the earth's field.
