1. an area or open space, as an operative field or visual field.
2. a range of specialization in knowledge, study, or occupation.
3. in embryology, the developing region within a range of modifying factors.
auditory field the space or range within which stimuli will be perceived as sound.
disturbed energy field a nursing diagnosis defined as a disruption of the flow of energy surrounding a person's being that results in disharmony of the body, mind, and/or spirit.
energy field the flow of energy surrounding a person.
extended field in radiation therapy, such as for malignant lymphoma, an area of irradiation beyond the involved field. See also under irradiation.
high-power field the area of a slide visible under the high magnification system of a microscope.
individuation field a region in which an organizer influences adjacent tissue to become a part of a total embryo.
inverted Y field in radiation therapy, such as for malignant lymphoma, a circumscribed area of irradiation below the diaphragm, covering the spleen, extending down the midline, and branching inferiorly to form tails across the inguinal areas.
involved field in radiation therapy, such as for malignant lymphoma, the irradiated area when irradiation has been limited to sites of detectable macroscopic disease. See also under irradiation.
low-power field the area of a slide visible under the low magnification system of a microscope.
magnetic field that portion of space about a magnet in which its action is perceptible.
mantle field in radiation therapy, such as for malignant lymphoma, a circumscribed area of irradiation around the shoulders and chest, including the neck, clavicular regions, axillae, and mediastinum. See also under irradiation.
morphogenetic field an embryonic region out of which definite structures normally develop.
operating field (operative field) an isolated area where surgery is performed; it must be kept sterile by aseptic techniques (see surgical asepsis). Called also surgical field.
sterile field an operative field that is properly sterile according to surgical asepsis. It includes having all furniture and equipment covered with sterile drapes and all personnel being properly attired.
surgical field operative field.
visual field (F) (vf) the area within which stimuli will produce the sensation of sight with the eye in a straight-ahead position.

mag·net·ic field

the sphere of influence of a magnet.

magnetic field

Etymology: Gk, magnesia, lodestone; AS, feld
the region around any magnet in which its effects can be detected.

magnetic field

An MRI term for the magnetic lines of force (flux) which extend from a north polarity and enter a south polarity of a magnet to form a closed loop around the outside of a magnetic material.

Magnetic field

The three-dimensional area surrounding a magnet, in which its force is active. During MRI, the patient's body is permeated by the force field of a superconducting magnet.

magnetic field (MF),

n the lines of force that surround a moving charged particle or a magnet.

6 shows the lines of equal level of the magnetic flux density module: a) of the initial MF created by several TL and b) with the active screening system turned on.
The longitudinal component of magnetic flux density within pipe at control zone (above the coil) was calculated.
The proposed model further suggests that in presence of a magnetic field, the equivalent circuit representing the neuronal plasma membrane may be expanded by including a magnetic-field-dependent current source whose magnitude is proportional to the magnetic flux density.
which is the well known expression for the magnetic flux density of a straight conductor
magnetic flux density (30, 62,5, 125, 200, 250) mT and time exposition (0,5, 1, 3, 5, 10, 15, 20, 25, 30, 60) minutes; combinations of factor generate 51 groups, taking into account a control group, without magnetic exposition; to each group were used 80 seeds.
On the basis of magnetic flux density in w-coordinates, the distribution of magnetic flux density in z-coordinates (in the air gap) will be obtained:
On the other hand modern technology permits to manufacture traps from permanent magnets with not much smaller values of the magnetic flux density B and one may use a normal solenoid as a magnetic shutter.
The electric signal generated by the moving coil is expressed in terms of magnetic flux density, length of coil wire and velocity of the coil as;
This, in turn, permits minimization of the air gap between the magnet return structure and the permanent magnet, maximizing the magnetic flux density of the motor and producing greater torque.
The drive uses AME technology where the magnetic layers are made of 100% cobalt material, a recording surface with twice the magnetic flux density of coated media, offering improved levels of recording density and recording system performance.
Two important terms in relation to ferrite-based components are magnetic field intensity (H) and magnetic flux density (B).
