A magnetic meridian is a curvy line, running from the north magnetic pole to the south magnetic pole. magnetic south pole, for example - don't match exactly. poles. Magnetic Equator : An imaginary line, right bisecting the effective length of a magnet is called magnetic equator. A magnetic meridian lies parallel with the magnetic lines of force of the earth. It is called easterly (E) if the compass needle, aligned with the magnetic meridian, points eastward or to the right of true north, and westerly (W), if it points to the left The magnetic equator passes through India, near Trivandrum, Kerala. The 40th meridian, for example, has … Magnetic meridian is the line that is parallel to the direction taken by a freely moving magnetized needle. The magnetic axis of the earth is inclined at 20° to its geographical axis. … The meridians run from north pole to south pole. B) Every meridian is actually a circle rather than a curved line. However, a compass needle will not be steady in the magnetic meridian, because of the longitude from east to west being complete geodesic.
