Sentences with phrase «magnetic dipole»
A magnetic dipole is a term used to describe a basic magnetic component, such as a small magnet or an electric current loop, that has two opposite poles (north and south). These poles create a magnetic field around the dipole. The term "dipole" refers to the fact that it has two poles. This magnetic field can attract or repel other magnets or magnetic materials.

The DCRS is composed of two (transmitting and receiving) magnetic dipole coils, placed in parallel, with each coil having a ferrite core and connected with a resonant capacitor.
If space were a vacuum, then the Sun's 10 - 4 tesla magnetic dipole field would reduce with the cube of the distance to about 10 - 11 tesla.
Despite the absence of a global Earth - like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet.
Unlike Earth, Mars has no global magnetic dipole, but the solar wind instead induces currents in the ionized upper atmosphere (the ionosphere), creating an induced magnetosphere.
To be more precise, the particle must carry a small magnetic dipole moment.
«We think we've got a much more complicated magnetic field than the simple magnetic dipole model.»
Allowed quadrupole and magnetic dipole transitions are allowed but are vanishingly weak, let alone the overtones thereof.
This process creates a current of magnetic dipoles that we use to manipulate the orientation of a second magnetic layer,» said David Cahill, a Donald B. Willett Professor of Engineering and head of the Department of Materials Science and Engineering at Illinois.
In fact the magnetic dipole is shifted from the center of the planet towards the south rotational pole by as much as one third of the planetary radius.
Simply put, the «spin» can be interpreted as a magnetic dipole that can point in two directions («up» and «down»).
Paul realized that it is possible to design a magnetic field with a local minimum in the field strength, and if the magnetic dipole is originally aligned to seek a position where the field is weakest, it will remain aligned in the «weak field - seeking» orientation [see «Cooling and Trapping Atoms,» by W. D. Phillips and H.].
Notice that this force is analogous to the magnetic dipole force first used to trap neutrons and atoms.
Latitude (top) and longitude (bottom) of the northern geomagnetic pole location represent tilt and tilt direction of the magnetic dipole axis.
