Zane · Answer 1

0.212 Wb

Explanation:

Area = π r² = π (0.072) ² = 0.01628 m²

Magnetic field given = B = 13 T

Magnetic flux is the dot product of the Area of cross section and the magnetic field.

Magnetic flux is the number of field lines that pass through a given surface.

Ф = B. A cos θ here θ is the angle between the magnetic field lines and the normal perpendicular to the surface.

Ф = (13) (0.01628) = 0.212 Wb
