* 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.

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

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 field of an ideal cylindrical magnet with its axis of symmetry inside the image plane.

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 field immunity.

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

Magnetic lines of force are parallel to the geometric axis of this structure.

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.

By 1915, electricity lines ran from Magnetic Springs to Richwood.

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 ).

Magnetic flow meters, often called " mag meter " s or " electromag " s, use a magnetic field applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines.

Magnetic reconnection is the name given to the rearrangement of magnetic field lines when two oppositely directed magnetic fields are brought together.

As of 2004, two Magnetic Flagman wigwags in the US remain at main rail lines.

Magnetic field lines around a " magnetostatic dipole " the magnetic dipole itself is in the center and is seen from the side.

Magnetic field lines in a plane bisecting the current loops.

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 permeability is typically represented by the Greek letter μ.

* Magnetic Arrowhead ( adheres to metal surfaces ; can be added to other arrows )

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 fields are the cause of the force associated with magnets.

* Magnetic phonograph cartridges, which have a mu-metal case to reduce interference when LPs are played back

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

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 core, in electricity and electronics, ferromagnetic material around which wires are wound

Magnetic tapes, diskettes, and non-printed punched paper tapes are not hard copies.

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

Magnetic fields are ubiquitous among stars, yet we do not understand precisely why, nor have we fully understood the bewildering variety of plasma physical mechanisms that act in stellar environments.

Magnetic sound stripes are shown in gray.

Magnetic ferrofluids, although they are made of tiny ferromagnetic particles suspended in liquid, are sometimes considered paramagnetic since they cannot be magnetized.

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.

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

Magnetic gradiometers are pairs of magnetometers with their sensors separated, usually horizontally, by a fixed distance.

Magnetic materials in the sensor itself are the primary cause of this error.
