The new model, combining sight, motion and sound was dubbed the Magnetic Flagman, with production by the Magnetic Signal Company of Los Angeles, though history is unclear as to exactly when the changeover to Magnetic Signal took place.

Until toppled by a truck in April 2004, a lower-quadrant Magnetic Flagman wigwag protected a private crossing of a BNSF main mostly hidden from public view by a sound barrier in Pittsburg, California.

Magnetic stripes could be added to carry encoded sound to be added after film development.

Magnetic sound prints were expensive, 35mm magnetic prints cost roughly twice as much as optical sound prints, whilst 70mm prints could cost up to 15 times as much.

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 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.

; 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.

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.

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.

Magnetic analyses by R. G. Meisenheimer of this laboratory indicated no ferromagnetic impurities.

Magnetic dipoles are best represented as loops of current but resemble positive and negative ' magnetic charges ', inseparably bound together, having no net ' magnetic charge '.

Magnetic tape or disk " card-image " files created from such card decks often had no line-separation characters at all, commonly assuming fixed-length 80-character records.

Magnetic fields are used for confinement since no solid material could withstand the extremely high temperature of the plasma.

This has largely influenced the reserved live setup of The Magnetic Fields, which usually consists of acoustic instruments and little to no percussion.

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

Magnetic bearings support moving machinery without physical contact ; for example, they can levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear.

Magnetic bearings support the highest speeds of any kind of bearing ; they have no known maximum relative speed.

* Magnetic ( no wear ), direct drive ( low slip ) mechanism.

Later, a Canada-based record company called Magnetic Air Productions issued a pirate ( bootleg ) release worldwide, under a different cover, with no royalties being paid to the band.

The market for word processing equipment was shifting to magnetic media such as IBM ’ s revolutionary Magnetic Tape Selectric Typewriter ( MTST ), and paper tape based solutions were no longer able to compete.

Magnetic bones have been found in the human nose, specifically the sphenoidal / ethmoid sinuses Beginning in the late 1970s, the group of Robin Baker at the University of Manchester began to conduct experiments that purported to exhibit magnetoception in humans: people were disoriented and then asked about certain directions ; their answers were more accurate if there was no magnet attached to their head.

Magnetic Resonance guided Focused Ultrasound, is a non-invasive intervention ( requiring no incision ) that uses high intensity focused ultrasound waves to destroy tissue in combination with magnetic resonance imaging ( MRI ), which guides and monitors the treatment.
