Question

10. (4 points) Eight identical rectangular wire loops are moving to the right in the vicinity of a region in which there is a uniform magnetic field coming out of the page. The rectangular loops are being pushed to the right all at the same constant speed. The loops have various portions (25%, 50%, 75%, or 100%) within the field as shown. Rank the magnitude of the rate of change of magnetic flux through the rectangular loops at the positions shown. Assume there is no interaction between the loops. O o o o bé ojo ooooooooo Do pop po oo bo ob pedoo o o o o o o o o OGO | O bdo oo TOOoooooooo OOooo IH All loops moving to the right Greatest 1_ 2_ 3__ 4__ 5__ 6_ 7__ 8__ Least

Explanation / Answer

The speed of their movement is same. So, rate of change of magnetic flux is directly proportional to change in area of loop that is inside the field. So, F>A=G=C>D=E=H=B
