Question

The Earth's magnetic field passes through a square tabletopwith a magnitude of
4.95 × 10–5 T and directed at anangle of 165° relative to the normal of the tabletop. If thetabletop has 1.50-m sides, what is the magnitude of the magneticflux through it?

b. 1.08 ×10–4 Wb
c. 1.92 ×10–5 Wb
d. 7.11 ×10–5 Wb
e. 3.30 × 10–6 Wb The Earth's magnetic field passes through a square tabletopwith a magnitude of

Explanation / Answer

          Given that the magnitude of magnetic field is B =4.95*10-5 T           The angle is = 1650            Lengthfo each side is L = 1.50m -------------------------------------------------------------------------        The magnetic flux is = B.A                                          =BAcos                                          =B*L2*cos                                              =-------------- Wb                    Lengthfo each side is L = 1.50m -------------------------------------------------------------------------        The magnetic flux is = B.A                                          =BAcos                                          =B*L2*cos                                              =-------------- Wb
