Question

A magnetic field of magnitude 0.41 T isdirected vertically upward. (a) Find the magnetic flux through a flatsurface of area 19 cm2 if thesurface is vertical.
(b) Find the magnetic flux through a flat surface of area 19cm2 if the surface is horizontal. (c) Find the magnetic flux through a flatsurface of area 19 cm2 if the surface is at angle of56° with the horizontal.
(a) Find the magnetic flux through a flatsurface of area 19 cm2 if thesurface is vertical.
(b) Find the magnetic flux through a flat surface of area 19cm2 if the surface is horizontal. (c) Find the magnetic flux through a flatsurface of area 19 cm2 if the surface is at angle of56° with the horizontal.

Explanation / Answer

Magnetic field B = 0.41 T

Area A= 19 cm ^ 2= 19 * 10 ^ -4 m^ 2

(a). Magnetic flux = BA cos 90 = 0

(b). magnetic flux = BA cos 0

                             = BA

                             = 7.79 * 10 ^ -4 Wb

(c). Magnetic flux = BA cos 56

                              = 4.356 * 10^ -4 Wb
