MAGNETIC FIELD
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
The lines of force surrounding a permanent magnet or a moving charged particle
Synonyms:
flux; magnetic field; magnetic flux
Classified under:
Nouns denoting natural phenomena
Hypernyms ("magnetic field" is a kind of...):
field; field of force; force field (the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it)
Hyponyms (each of the following is a kind of "magnetic field"):
magnetosphere (the magnetic field of a planet; the volume around the planet in which charged particles are subject more to the planet's magnetic field than to the solar magnetic field)
solar magnetic field (the magnetic field of the sun)
Context examples:
The discovery could help scientists better understand how brown dwarfs generate magnetic fields.
(Powerful Auroras Found at Brown Dwarf, NASA)
Changing current and concomitantly magnetic fields
(Electromagnetic Flux, NCI Thesaurus)
Testing the static magnetic field gradients on medical imaging devices for their ability to induce heat in objects.
(Device Radiofrequency Induced Heat Testing Evaluation Method, Food and Drug Administration)
However, the performance of prototype devices has been limited to date, as the thermal changes are driven by limited magnetic fields from permanent magnets.
(Electronic solid could reduce carbon emissions in fridges and air conditioners, University of Cambridge)
Testing the static magnetic field gradients on medical imaging devices for their ability to rotate objects.
(Device Magnetically Induced Torque Testing Evaluation Method, Food and Drug Administration)
Testing the static magnetic field gradients on medical imaging devices for their ability to move objects.
(Device Magnetically Induced Displacement Force Testing Evaluation Method, Food and Drug Administration)
This is because the neutron star’s intense magnetic field pulls the particles from the pulsar’s surface and accelerates them to nearly the speed of light.
(NASA’s Fermi Mission Links Nearby Pulsar’s Gamma-ray ‘Halo’ to Antimatter Puzzle, NASA)
The branch of physics concerned with the study of the interaction of magnetism with electrical currents and the properties of the currents and magnetic fields that are generated.
(Electromagnetism, NCI Thesaurus)
When exposed to a strong external magnetic field, ferumoxides exhibits enhanced T2 relaxation, resulting in signal loss in normal tissues (image darkening) on mid T1/T2 or strongly T2-weighted images.
(Ferumoxides Injectable Solution, NCI Thesaurus)
Radiation that has both electric and magnetic fields and travels in waves.
