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

* Magnetic field

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.

Magnetic shielding made with high permeability alloys like mu-metal works not by blocking magnetic fields but by providing a path for the magnetic field lines around the shielded area.

Magnetic field gradients cause nuclei at different locations to rotate at different speeds.

Magnetic field lines represent the magnetic field surrounding Earth.

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.

Magnetic pressure should tend to remove field concentrations, causing the sunspots to disperse, but sunspot lifetimes are measured in days or even weeks.

Superconducting Magnetic Energy Storage ( SMES ) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature.

: Magnetic flux in a ferromagnetic material, such as the core, causes it to physically expand and contract slightly with each cycle of the magnetic field, an effect known as magnetostriction.

Magnetic confinement fusion devices exploit the fact that charged particles in a magnetic field feel a Lorentz force and follow helical paths along the field lines.

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.

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

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

* Magnetic pole, one of the two ends of a magnet

** Magnetic monopole, a hypothetical particle that may be loosely described as a magnet with only one pole

" Von Guericke was aware of both Gilbert's book " On the Magnet and Magnetic bodies and on the great magnet the Earth " published in 1600 and of the Jesuit Niccolo Cabeo's " Philosophia Magnetica " ( 1629 ).

Magnetic field # Magnetic field lines | Magnetic field lines of a solenoid electromagnet, which are similar to a bar magnet as illustrated above with the iron filings

The north pole of a magnet is the pole that, when the magnet is freely suspended, points towards the Earth's North Magnetic Pole which is located in northern Canada.

* Magnetic monopole is a hypothetical particle that may be loosely described as " a magnet with only one pole ".

The most powerful electromagnet in the world, the 45 T hybrid Bitter-superconducting magnet at the US National High Magnetic Field Laboratory, Tallahassee, Florida, USA

Refrigerators based on the magnetocaloric effect have been demonstrated in laboratories, using magnetic fields starting at 0. 6 T up to 10 T. Magnetic fields above 2 T are difficult to produce with permanent magnets and are produced by a superconducting magnet ( 1 T is about 20, 000 times the Earth's magnetic field ).

* Magnetic monopole, or Dirac monopole, a hypothetical particle that may be loosely described as a magnet with only one pole, or related concepts in physics and mathematics:

* The Magnetic Field Design ( MFD ) pickups use a ceramic bar magnet in combination with soft iron pole pieces with adjustable height, instead of the traditional Alnico magnet, and allow a player to set the pickup output per string, as opposed to the entire pickup as a whole in traditional single-coil pickup designs.

Magnetic nail polish is often used to create patterns on the nails using a magnet.

Magnetic remanence is often identified with a particular kind of remanence that is obtained after exposing a magnet to a field at room temperature.

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.

The National High Magnetic Field Laboratory ( NHMFL ) is the world's highest powered magnet laboratory, located in Tallahassee, Florida.

The impression that he made that year, resulted in many invitations to perform with world known artists like Public Enemy, Stetsasonic, Ice T and Ultra Magnetic MCs.

Magnetic fields are the cause of the force associated with magnets.

: Magnetic resistance models control resistance by means of electromagnets that engage a mechanical brake with the flywheel.

In the early days of nuclear magnetic resonance he studied the underlying theory, and in 1959 he coauthored the text book High Resolution Nuclear Magnetic Resonance with W. G.

In the Soviet Union, Vladislav Ivanov filed ( in 1960 ) a document with the USSR State Committee for Inventions and Discovery at Leningrad for a Magnetic Resonance Imaging device, although this was not approved until the 1970s.

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

It should not be confused with the North Magnetic Pole.

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 fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.

Magnetic sails could also be used with beam-powered propulsion by using a high-power particle accelerator to fire a beam of charged particles at the spacecraft.

With support of the National Science Foundation, LANL operates one of the three National High Magnetic Field Laboratories in conjunction with and located at two other sites Florida State University in Tallahassee, Florida and University of Florida in Gainesville, Florida.

Magnetic interactions with ionized gas could be responsible for shaping some planetary nebulae.

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

Magnetic moment displacement is ostensibly the main disturbance, yet submarines are detectable even when oriented parallel to the Earth's magnetic field, despite construction with non-ferromagnetic hulls.

In a publication The Magnetic Fields ( Les Champs Magnétiques ), a collaboration with Soupault, he implemented the principle of automatic writing.

Through its Magnetic Peripherals unit, originally a joint venture with Honeywell and Honeywell Bull, CDC became a major player in the hard disk drive market.
