Magnetic Pole

</dt>
1. Either of the two places on the surface of the earth where the magnetic dip is 90 �, that in the Northern Hemisphere (at, approximately, latitude 73� 8 N, longitude, 101� W in 1955) being designated north magnetic pole , and that in the Southern Hemisphere (at, approximately, latitude, 68� S, longitude, 144� E in 1955) being designated south magnetic pole. Also called dip pole. See geomagnetic latitude, geomagnetic pole, magnetic latitude. </dd>
2. Either of those two points of a magnet where the magnetic force is greatest. </dd>
3. In magnetic theory, a fictitious entity analogous to a unit electric charge of electrostatic theory. In nature only dipoles, not isolated magnetic poles, exist. [[/a>|/a> ]]
