... far beyond the scope of FLAP. At the present time many of the theories which aim to describe the nature of the fundamental constituents of all forms of matter, i.e. the ‘elementary particles’ of nature, do predict the existence of particles that have the magnetic properties of isolated poles.

User Guide for FMT1000-series Magnetic Field Mapper
... A Fairchild Motion Tracker (FMT) can be used to easily and accurately record 3D orientation. When a FMT is mounted to an object that contains ferromagnetic materials, the measured (Earth) magnetic field is distorted (warped) and causes an error in measured orientation if the magnetometers are used t ...

Solving Systems by Elimination
... eliminate the y by adding the two equations. The result is one equation that has only one variable: 6x = –18. When you use the elimination method to solve a system of linear equations, align all like terms in the equations. Then determine whether any like terms can be eliminated because they have op ...

Stability of accretion discs threaded by a strong magnetic field
... One may wonder when the approximation of height-independent velocity fields in the disc is justified. The assumption clearly eliminates the possibility of dynamo generation of magnetic fields, but is appropriate for strong fields in the sense discussed in the preceding section, namely fields which c ...

... With the magnetic field pointing downward and the area vector A pointing upward, the magnetic flux is negative, i.e., ! B = " BA < 0 , where A is the area of the loop. As the magnet moves closer to the loop, the magnetic field at a point on the loop increases ( dB / dt > 0 ), producing more flux thr ...

Dielectric
... We just saw that the energy is reduced by the introduction of a dielectric. Since systems want to reduce their energy, the dielectric will be sucked into the capacitor. Alternatively, since opposing charges are induced on the dielectric surfaces close to the plates, the attraction between these will ...

Magnetic Field Angle Effects on Sheath Formation near a Flat Plate
... corresponds to a similar reduction in erosion rate. Another influence on sheath formation, from Ref. 1, includes the applied, perpendicular to the wall, electric field potential between the Hall Thruster anode and cathode. An electric potential, E⊥ , of 20 kV /m was used, and reducing this lead to a t ...
