# Magnetic techniques, including aeromagnetic surveys.

Magnetic and electromagnetic surveys can be used to locate unexploded ordnance.

Magnetic hyperthermia makes use of magnetic nanoparticles, which can be injected into tumours and then generate heat when subjected to an alternating magnetic field.

Magnetic domains can be observed with a magnetic force microscope to reveal magnetic domain boundaries that resemble white lines in the sketch.

It turns out that the magnetic barrier can be broken down by electric forces, as discussed in Magnetic Storms and Plasma Flows ( MSPF ).

Magnetic bottles can be used to temporarily trap charged particles.

Magnetic susceptibility can be measured as function of temperature to establish whether the material is a para -, ferro-or antiferro-magnet.

Magnetic fields are produced on poles, and these can be salient poles where they are driven by windings of electrical wire.

Magnetic pole strength of electromagnets can be found from:

Magnetic data and space weather forecasts can also be helpful in clarifying unknown sources of drilling error on an on-going basis.

They can migrate rapidly: movements of up to km per year have been observed for the North Magnetic Pole.

Magnetic tweezers can measure femtonewton forces, and additionally they can also be used to apply torsion.

Magnetic field lines only exist as loops, they cannot diverge from or converge to a point like electric field lines can ( see Gauss's law for magnetism ).

Following statistical analysis, the results are used to generate a local magnetostratigraphic column that can then be compared against the Global Magnetic Polarity Time Scale.

Magnetic response M is dependent upon the orientation of the sample and can occur in directions other than that of the applied field H. In these cases, volume susceptibility is defined as a tensor

Magnetic resonance can mean:

Magnetic stripe cloning can be detected by the implementation of magnetic card reader heads and firmware that can read a signature of magnetic noise permanently embedded in all magnetic stripes during the card production process.

Magnetic sensing can only be applied to detect huge masses of iron such as ships.

Magnetic induction ( for example, in a transformer ) can be seen a very simple model of this type of near-field electromagnetic interaction.

Previous attempts at deep brain stimulation-Terri Schiavo being one of the patients-failed to restore consciousness. This kind of stimulation can also be guided by results of Transcranial Magnetic Stimulation ( TMS ) as this was able to transitorily improve a patient in PVS ( Dr Pape, Chicago 2009 ) and another in the minimally conscious state ( 2010 ).

An aircraft can follow a specific path from station to station by tuning in to the successive stations on the VOR receiver, and then either following the desired course on a Radio Magnetic Indicator, or setting it on a Course Deviation Indicator ( CDI ) or a Horizontal Situation Indicator ( HSI, a more sophisticated version of the VOR indicator ) and keeping a course pointer centered on the display.

The music of Stephin Merritt can also be heard throughout the series, including songs from his projects The Magnetic Fields, The 6ths and The Gothic Archies.

The report concludes that a small percentage of sightings that can not be easily explained are caused by atmospheric plasma phenomenon similar to ball lightning ; Magnetic and other energy fields produced by these " buoyant plasma formations " are responsible for the appearance of so-called " Black Triangles " as well as having hallucinogenic effects on the human mind, inducing experiences of Close Encounters.

Magnetic tickets are still sold, for the occasional riders, however they are now in a paper form and can only be purchased with cash.

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 flux from the surroundings ( such as other wires ) may diminish or enhance the field the Hall probe intends to detect, rendering the results inaccurate.

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.

The Finnish Meteorological Central Office ( 1881 ) was formed from part of Magnetic Observatory of Helsinki University.

Magnetic fields in the magnetosphere arise from the Earth's internal magnetic field as well as from electric currents that flow in the magnetospheric plasma: the plasma acts as an electromagnet.

Magnetic fields from currents that circulate in the magnetospheric plasma extend the Earth's magnetism much further in space than would be predicted from the Earth's internal field alone.

In May 1845 the Magnetic Telegraph Company was formed in order to radiate telegraph lines from New York City towards Philadelphia, Boston, Buffalo, New York and the Mississippi.

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.

Values used by mobile stations usually need to be converted from Magnetic to True.

Magnetic field lines, represented as arrows, are excluded from a superconductor when it is below its critical temperature.

Image: Tin_80gauss_1. 6K. jpg | The cylinder has been cooled from 4. 2 K to 1. 6 K. The current in the electromagnet has been kept constant, but the tin became superconducting at about 3 K. Magnetic flux has been expelled from the cylinder ( the Meissner effect ).

Satellite, near-surface and oceanic data from detectors was used to create the World Digital Magnetic Anomaly Map published by the Commission for the Geological Map of the World ( CGMW ) in July 2007.

The show included two tracks from the then-forthcoming Scratch My Back: Paul Simon's " The Boy in the Bubble " and The Magnetic Fields ' " The Book of Love ".

Magnetic south is the direction towards the south magnetic pole, some distance away from the south geographic pole.

Magnetic fields from magnetic bodies of ore fall off with the inverse distance cubed ( dipole target ), or at best inverse distance squared ( magnetic monopole target ).
