Question

Eight identical rectangular wire loops are moving to the 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 at various constant speeds as indicated in the diagram. The loops have various portions (25, 50%, 75%, or 100%) within the field as shown. The rectangular loops are all 5 cm by 10 cm. 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. Greatest 1 _______ 2 _____ 3 _______ 4 ______ 5 ________ 6 ___________ 7 ___________ 8 _________ Least OR, all the loops have the same (but not zero) rate of change of magnetic flux. ___________ OR, the rate of change of magnetic flux is zero for all of the loops. __________ OR, the ranking for the rate of change of magnetic flux cannot be determined. _______ Carefully explain your reasoning.

Explanation / Answer

according to faraday's law ,rate of change of magnetic lux is equal to induced emf

indued emf is e = B*l*v

for A) e = B*l*v = B*5*2 = 10*B

B) e = B*8*5 = 40*B

C) e = B*5*5 = 25*B

D) e = B*5*6 = 30*B

E) e = B*10*6 = 60*B

F) e = B*10*2 = 20*B

G) e = B*6*5 =30*B

H) e = B*10*6 = 60*B

Greatest to smallest

H) = E) > B) D) = G) > C) > F) > A)

loops have the same rate of change o magnetic flux are H and E , D and G
