    Answer:

    1.15 * 10^(-5) Tm²

    Explanation:

    Parameters given:

    Magnitude of magnetic field, B = 5.7 * 10^(-5) T

    Angle of magnetic field to the horizontal plane = 73°

    Dimension of the desk = 81 cm × 85 cm

    Area of desk, A = 6885 cm² = 0.6885 m²

    The magnitude of the Magnetic Flux, |Φ|, is given as:

    |Φ| = |B * A * cosθ|

    Where θ = angle of the Magnetic field to the normal of the desk = 90 – 73 = 17°

    Therefore, the magnitude of the Magnetic Flux will be:

    |Φ| = |5.7 * 10^(-5) * 0.6885 * cos17|

    |Φ| = 3.75 * 10^(-5) Tm²
