    The magnetic flux is 0.028 T. m²

    Explanation:

    Given;

    magnetic field strength, B = 1.4-T

    cross sectional area, A = 200 cm²

    Area in m² = 200 cm² x (1m/100cm) ²

    = 200 cm² x 1m²/10000cm²

    = 200 m² / 10000

    = 0.02 m²

    To determine the magnetic flux through your head when the magnetic field is 1.4-T, we apply magnetic flux equation below;

    Φ = BA

    Where;

    Φ is the magnetic flux

    B is the magnetic field

    A is area

    Φ = BA

    Φ = 1.4 x 0.02 = 0.028 T. m²

    Therefore, the magnetic flux through your head is 0.028 T. m².
