What is the X in X-mas?
|magnetic pole |
The spot on the Earth toward which a compass needle will point.
Note: The north magnetic pole is not located exactly at the geographic North Pole. Therefore, depending on where a compass is, its needle may not point exactly north.
Note: The variation between magnetic north and “true” north is usually shown on navigation maps as the “angle of declination.”
region at each end of a magnet where the external magnetic field is strongest. A bar magnet suspended in the Earth's magnetic field orients itself in a north-south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. The south-seeking pole, or any pole similar to it, is called a south magnetic pole. Unlike poles of different magnets attract each other; like poles repel each other
