A 10-cmcm-diameter circular loop of wire is placed in a 0.73-TT magnetic field. When the plane of the loop is perpendicular to the field lines, the magnetic flux through the loop will be 0.0057 Wb
Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total magnetic field that passes through a given surface area.
Diameter = 10 cm
Radius = 5 cm = .05 m
Area = π[tex]r^{2}[/tex] = 3.14 * .05 * .05 = 0.00785 [tex]cm^{2}[/tex]
Magnetic field = 0.73 T
when the plane is perpendicular to the field lines , angle (theta) = 0 °
Flux = BA cos ( theta)
= 0.73 * 0.00785 * cos ( 0° )
= .0057 Wb
