    -1.9 * 10-5 Wb

    Explanation:

    Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux

    Finding the area

    Area = πr² = 3.14*0.075*0.075

    Area=0.01767 m²

    Magnetic flux = 0.01767*0.00110*cos 0

    Magnetic flux = 0.000019 = - 1.9 * 10-5 Wb
