    Ф = 2.51mWb

    Explanation:

    Given Area 7.8cm by 14cm = 109.2cm² = 109.2*10-⁴m²

    B = 0.23T.

    Ф = BACosθ

    Ф = magnetic flux through the area.

    B = magnetic field strength

    A = Area of the loop through which there is a magnetic flux.

    θ = angle between the normal to the area and the direction of the magnetic field. The normal is a perpendicular line directed out of the plane of the loop. It is a vector for the area.

    Assuming that the normal to the area is perpendicular to the magnetic field vector, that is θ = 0°,

    Ф = 0.23 * 109.2*10-⁴ Cos0° = 2.51*10-³Wb = 2.51mWb.
