exists and is an alternate of . A boggy uterus is one that has a soft, mushy feel to it. A normal uterus, one that's not boggy, feels firm, like a muscle that's being flexed.
The angle between the compass needle and geographic north is called the magnetic declination (see Earth: The magnetic field of the Earth). The repulsion or attraction between two magnetic dipoles can be viewed as the interaction of one dipole with the magnetic field produced by the other dipole. The magnetic field is not constant, but varies with the distance from the dipole.
And that's where the names come from. The 'North pole' of any magnet is the one that would be attracted to the Earth's North magnetic pole. In that sense, they are just labels that identify the opposite magnetic force produced at each end of the magnet. The Earth's magnetic field also has poles, North and South.
