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.
Magnets, created by spinning electrons, are used to perform useful work in motors and generators every day. The magnetic gradient (dB/dx) or changing magnetic field is known from classical physics to create a force in one direction, similar to but better than a linear motor.he principle of a magnetic gradient force is converted from the linear case to dB/dÎ¸ in the circular case. The radial magnetic field increases its attraction as the rotor turns through one complete cycle. (Valone, 2005)Note that this model is designed in the attractive mode.
