An experiment to determine the local magnetic field of the Earth uses a coil consisting of 210 individual loops, each of area 12.7 cm2 . The coil is rotated and the resultant induced EMF is used to determine the magnetic field. The coil is rotated in a time interval of 4.90×10−2 s from a position where its plane is perpendicular to the earth's magnetic field to one where its plane is parallel to the field. The earth's magnetic field at the...
