# Magnetic poles ( or states of polarization at individual points ) attract or repel one another in a similar way and always come in pairs: every north pole is yoked to a south pole.

The Earth's North Magnetic Pole ( currently in the Arctic Ocean, north of Canada ) is physically a south pole, as it attracts the north pole of a compass.

** South Magnetic Pole, the shifting point on the Earth to which the " south " end of a dipole magnet points

Since opposite poles ( north and south ) attract, the Earth's " North Magnetic Pole " is thus actually the south pole of the Earth's magnetic field.

** The South Magnetic Pole of planet Earth, a point where the south end of a compass points upward

Magnetic media, on the other hand, always carries a magnetic flux-either a " north " pole or a " south " pole.

Magnetic Island became an important defensive position during World War II due to its proximity to Townsville, an important military base, and its views over Cleveland Bay, a significant anchorage and assembly point for large fleets and convoys operating in the south Pacific.

In his book he listed the expedition's main achievements: proof that an expedition could live on Victoria Land over winter ; a year's continuous magnetic and meteorological observations ; an estimate of the current position of the South Magnetic Pole ; discoveries of new species of insects and shallow-water fauna ; coastal mapping and the discovery of new islands ; the first landing on Ross Island and, finally, the scaling of the Great Ice Barrier and the sledging to 78 ° 50 ' S, " the furthest south ever reached by man ".

Mansun's third studio album, Little Kix ( early working titles included Magnetic Poetry and later The Trouble With Relationships ,) saw Draper and Chad decamp to the south of Spain in March 1999 where they wrote and demo'd ideas for the album.

Early in the spring of 86 BC Taxiles concentrated most of his troops, sent word to Archelaos to join him in the Magnetic ports, and marched south from Macedonia into Thessaly.

East Antarctica is the larger part of the continent, both the South Magnetic Pole and geographic South Pole are situated here.

Magnetic ( compass ) north and geographic ( true ) north are only exactly the same for a small number of places – for example, as of 2000 in the United States only those places on a line running from Wisconsin to the Gulf of Mexico .< ref > But the public may not be as informed, and think there is something mysterious about a compass " changing " across an area as large as the Triangle, which it naturally will.

* Magnetic resonance imaging ( MRI ) MRI is a method of imaging objects that uses a strong magnetic field to detect the relaxation of protons that have been perturbed by a radio-frequency pulse.

; Magnetic resonance angiography ( MRA ): This is similar to magnetic resonance imaging.

A live frog is Magnetic levitation | magnetically levitated, an experiment that earned Andre Geim from the University of Nijmegen and Sir Michael Berry ( physicist ) | Michael Berry from University of Bristol the 2000 Ig Nobel Prize in physics.

Magnetic resonance imaging ( MRI ), nuclear magnetic resonance imaging ( NMRI ), or magnetic resonance tomography ( MRT ) is a medical imaging technique used in radiology to visualize internal structures of the body in detail.

B ( r ) is the Magnetic field strength of the planet in SI units ( B in T, μ < sub > 0 </ sub > in H / m )

Magnetic reconnection in the near-Earth magnetotail, producing a disconnected " plasmoid " One possible scenario ( the subject is still debated ) is as follows.

Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic film.

* Magnetic levitation, a method by which an object is suspended using magnetic fields

Radboud University runs the High Field Magnetic Laboratory which is able to achieve some of the highest fields available in Europe at 33 teslas ( continuous ) and 60 teslas ( pulsed ).

The permanent moment generally is due to the spin of unpaired electrons in atomic or molecular electron orbitals ( see Magnetic moment ).

In the 1990s, researchers began to use Electroencephalography ( EEG ), Positron Emission Tomography ( PET ) and more recently functional Magnetic Resonance Imaging ( fMRI ), which is now the most widely used imaging technique to help localize personality traits in the brain.

This is a collection of fifteen selected non-fiction entries that had been published in Analog magazine over the years ; it includes five articles authored or co-authored by Zubrin, including " The Hypersonic Skyhook ", " Mars Direct: A Proposal for the Rapid Exploration and Colonization of the Red Planet " ( co-authored with David A. Baker ), " Colonizing the Outer Solar System ", " Terraforming Mars " ( co-authored with Christopher McKay ), and " The Magnetic Sail ".

Magnetic tape data storage is typically used for offline, archival data storage.

Magnetic tape is commonly housed in a casing known as a cassette or cartridge — for example, the 4-track cartridge and the compact cassette.

The treatment is often guided by Magnetic Resonance Imaging ( MRI ); the combination is then referred to as Magnetic resonance-guided focused ultrasound ( MRgFUS ).

* 1995: Madam Butterfly is the central piece of Magnetic Rose, an animated short produced by Katsuhiro Otomo and directed by Kōji Morimoto.

Magnetic mirrors play an important role in other types of magnetic fusion energy devices such as tokamaks, where the toroidal magnetic field is stronger on the inboard side than on the outboard side.

Remember too, that bearings and direction are given / recorded with respect to True North and to Magnetic North.

Magnetic north is of interest because it is the direction indicated as north on a properly functioning ( but uncorrected ) magnetic compass.

Magnetic circular dichroism ( MCD ) is the differential absorption of left and right circularly polarized ( LCP and RCP ) light, induced in a sample by a strong magnetic field oriented parallel to the direction of light propagation.

The term variometer also refers to a type of variable transformer or an instrument for measuring the magnitude and direction of a Magnetic field.

* Magnetic moment () is a dipole moment measuring the strength and direction of a magnetic source.

Magnetic declination is the angle between magnetic north ( the direction the north end of a compass needle points ) and true north.

Magnetic variation is the angle from magnetic north to true north ( positive in clockwise, easterly direction ) and is caused by the different locations of the Geographic North Pole and the Magnetic North Pole plus any local anomalies such as iron deposits.

* TM modes ( Transverse Magnetic ) no magnetic field in the direction of propagation.

The magnetic field between poles ( see figure for Magnetic pole definition ) is in the opposite direction to the magnetic moment ( which points from the negative charge to the positive charge ), while inside a current loop it is in the same direction ( see the figure to the right ).

The direction the thumb points tell us the direction current is flowing, the Magnetic field will be running 90 degrees from the current path.

* Magnetic north: The direction towards the North Magnetic Pole.

It is contrasted with true north ( the direction of the North Pole ) and magnetic north ( the direction of the Magnetic North Pole ).

Magnetic grains may precipitate from a circulating solution, or be formed during chemical reactions, and may record the direction of the magnetic field at the time of mineral formation.

Magnetic fields will act in a direction perpendicular to the electron propagation, thereby conserving velocity, whereas electrostatic fields will cause electrons to move along the field gradient, which may change electron energies if the component of the direction of propagation and field gradients are not perpendicular.

Although it is known that the Signal Department of the Pacific Electric Railway developed the first " Magnetic Flagman " wigwag signal, under the direction of a Mr. Albert Hunt ( some sources list him as J. B. Hunt ), it is not known at what point the Magnetic Signal Company became a separate entity.

Magnetic anisotropy, that is the existence of a easy direction along which the moments align spontaneously in the crystal, corresponds however to " massive " magnons.

The abstract with the first tractogram appeared at the August 1992 meeting of the Society for Magnetic Resonance in Medicine, Widespread research in the field followed a presentation on March 28, 1993 when Michael Moseley re-presented the tractographic images from the Filler group — describing the new range of neuropathology it had made detectable — and drew attention to this new direction in MRI at a plenary session of Society for Magnetic Resonance Imaging in front of an audience of 700 MRI scientists.
