Magnetic tape revolutionized broadcast and recording.

Magnetic tape was invented for recording sound by Fritz Pfleumer in 1928 in Germany, based on the invention of magnetic wire recording by Valdemar Poulsen in 1898.

Magnetic tape was first used to record computer data in 1951 on the Eckert-Mauchly UNIVAC I.

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 tape has a nonlinear response at low signal strengths, as measured by its coercivity.

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.

Magnetic disk and tape storage devices generally use fixed-rate RLL codes, while USB uses bit stuffing.

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 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 ".

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 tape: Magnetic tape has long been the most commonly used medium for bulk data storage, backup, archiving, and interchange.

Magnetic wire recording, and its successor, magnetic tape recording, involve the use of a magnetizable medium which moves past a recording head.

Magnetic storage and magnetic recording are terms from engineering referring to the storage of data on a magnetized medium.

Magnetic tapes consist of narrow bands of a magnetic medium bonded in paper or plastic.

Magnetic disks and drums include a rotating magnetic medium combined with a movable read / write head.
