Analysis of Flanged Section
Engineering Physics I - Earth's Magnetism
Earth’s Magnetism Our earth behaves as a powerful magnet whose south pole is towards earth’s north pole and north pole towards the earth’s south pole. It is clear from following evidences ( k|df0fx?+_ M a. A freely suspended magnetic needle stays in north-south direction. b. An iron piece buried in earth becomes magnet after a long time. c. Availability of neutral point. Elements of earth’s magnetism: There are three elements of earth’s magnetism. They are as follows: a. a. Angle of declination b. b. Angle of dip c. c. Horizontal component of earth’s magnetic field a. a. Angle of declination The acute angle between the magnetic meridian and the geographical meridian is called angle of declination. Magnetic meridian: The vertic...
