Find the average magnitude in Volts of the induced emf if the change in shape occurs in 4.26 s and the local 0.127 T magnetic field is perpendicular to the plane of the loop.
EDIT: Tried your answer and it was wrong

Area of square loop = (1.13)² = 1.2769 m²
Area(A) of circular loop with a circumference = 4(1.13) = 4.52m
A = πR² = π(4.52/2π)² = 1.6258 m²
delta A = 1.6258 - 1.2769 = 0.3489 m²
delta A/t = 0.3489/4.26 = 0.08190 m²/s
emf = B(detaA/t) = 0.127(0.08190) = 0.0104 v ANS

A unmarried undertaking loop of cord has a community of 8.0×10?2 m2 and a resistance of one hundred ? . Perpendicular to the plane of the loop is a magnetic container of power 0.50 T At what cost (in T/s) could this container replace if the led to present day in the loop is to be 0.35 A
