Document Summary
The direction of any magnetic field is defined as the direction the north pole of a magnet would point if placed in the field. The magfield of a magnet points from the north pole of a magnet to the south pole. The magnetic north pole of earth corresponds to the geographic south pole, and the magnetic south pole corresponds to the geographic north pole. The geographic north pole of the earth is near the magnetic ________ A magnometer senses the direction of the earth"s magnetic field and decides which torque coil to activate. Parallel to the earth"s surface, pointing from the geographic south pole (magnetic north) to the geographic north pole (magnetic south) In order to protect other equipment, the body of a satellite must remain unmagnetized, even when the torque coils have been activated. Hard magnetic material, because it is less easily magnetized.
