Answer:
0.02 V
Explanation:
Parameters given:
Area of coil, A = [tex]0.1 m^2[/tex]
Magnetic field, B = 0.2 T
Time taken for flip, t = 1 s
Angle of flip, θ = 180°
The average induced EMF in a coil of area, A, due to a changing magnetic field, B, is given as:
V = -BA(cosθ)/t
This is because the magnetic field has changed orientation by an angle θ.
Therefore, EMF induced will be:
[tex]V = \frac{-0.2 * 0.1 cos180}{1}\\ \\\\V = 0.2 * 0.2\\\\\\V = 0.02 V[/tex]
