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.
Between the magnetic poles there is an area called the magnetic equator where inclination or the magnetic dip angle is zero; the magnetic field vector does not have a vertical component (Z) in this area. To the north of the magnetic equator, the north end of the compass needle points downward, both I and Z are positive.
