Question

A circular loop of wire of radius r = 0.072 m is placed in a uniform magnetic field B = 13 T,with the plane of the loop perpendicular to the direction of the field, B . Calculate the magnetic flux through the loop. 0.021 Wb 0.293 Wb 0.212 Wb 0.179 Wb

Answer 1

0.212 Wb

Step-by-step 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
