Ch 27 hw exercise 27.12 10 of 20 constants a horizontal rectangular surface has dimensions 2.80 cm by 3.15 cm and is in a uniform magnetic field that is directed at an angle of 31.0 ∘ above the horizontal. part a what must the magnitude of the magnetic field be in order to produce a flux of 4.00×10−4 wb through the surface? express your answer with the appropriate units. bb = nothing nothing request answer provide feedback

Magnetic field, B = 0.88 T

Explanation:

It is given that,

The dimension of rectangular surface is 2.80 cm by 3.15 cm. The area of rectangular surface is,

Angle between the uniform magnetic field and the horizontal,

Magnetic flux,

Let B is the magnitude of magnetic field in which the rectangular surface is placed. It is given by :

is the angle between magnetic field and the area

Here,

B = 0.88 T

So, the magnitude of magnetic field is 0.88 T. Hence, this is the required solution.
