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.
There are four main electromagnetic interactions: 1  The force of attraction or repulsion between electric charges is inversely proportional to the square of the distance between them. 2  Magnetic poles come in pairs that attract and repel each other, much as electric charges do.
