Instructions1. In the three cases, use the average of the two angles ( = (+) + () =2), the averageof the two currents ( I = I(+) + I() =2), and Eqs. (1) and (2), and calculate coilÖeld and the earth ís horizontal component of magnetic Öeld, B(earth) H [ Tesla ].2. Based on the three previous calculations, what is your experimental determination ofthe horizontal component of the earthís magnetic Öeld, B(earth) H [ Gauss ]?3. Take the accepted value of the earthís horizontal component of magnetic Öeld in southFlorida to be 0:25 Gauss and calculate the percent error in your answer.

nent FULL SCREEN PRINTER VERSION K BACK NEXT Your answer is partially correct. Try again. The figure below shows a closed loop of wire that consists of a pair of equal semicircles, of radius 4,40 cm, lying in mutually perpendicular planes. The loop was formed by folding a flat circular loop along a diameter until the two halves became perpendicular to each other. A uniform magnetic field B of magnitude 97.0 mT is directed perpendicular to the fold diameter and makes equal angles (of 45.0°) with the planes of the semicircles. The magnetic field is reduced to zero at a uniform rate during a time interval of 28.5 ms. During this interval, what are the (a) magnitude and (b) direction (clockwise or counterclockwise when viewed along the direction of B) of the emf induced in the loop?
