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.
A magnetic pole is a point at either end of a magnetic field where the magnetic force is concentrated and strongest. The easiest way to visualize the poles of a magnet is by using a bar magnet, the kind you probably came across in a science class in school. That type of magnet is called a permanent magnet because its magnetic properties are constant. The two ends of a permanent magnet are its poles. The magnetic field surrounding the magnet and the force it exerts are depicted using curved lines with arrows called magnetic field lines.
