A generator can be made using the componentof Earth’s magnetic field that is parallel toEarth’s surface. A 110-turn square wire coilwith an area of 3.58 ×10−2 m2is mountedon a shaft so that the cross-sectional area ofthe coil is perpendicular to the ground. Theshaft then rotates with a frequency of 26.8Hz. The horizontal component of the Earth’smagnetic field at the location of the loop is4.00 ×10−5 T.
