Aclosely wound rectangular coil of 100 turns has dimensions of 27.0 cm by 50.0 cm . the plane of the coil is rotated from a position where it makes an angle of 37.0 ∘ with a magnetic field of 1.20 t to a position perpendicular to the field. the rotation takes 9.00×10−2 s . (note that the coil is perpendicular to the area vector of the coil.) what is the average emf induced in the coil?

induced.

Explanation:

We define all our variables,

EMF induced is given through the expression

Here we understand as

We proceed to calculate the entire Initial Flow as the final, as well

Final Flow

Now, if ,

induced.

NOTES:

It is necessary to make two small notes regarding the development of the exercise. The subtraction of the angles is used since the exercise indicates that the angle is between the field B and the Plane. However, the measurement between the Area and the field is required b.Negative signs can be neglected because it is understood that this is a reference to know which direction has the highest potential.
