magnetic field noun a region of space near a magnet, electric current, or moving charged particle in which a magnetic force acts on any other magnet, electric current, or moving charged particle. magnetic intensity.Discover More Word History and Origins Origin of magnetic field1 First recorded in...
The meaning of MAGNETIC FIELD is the portion of space near a magnetic body or a current-carrying body in which the magnetic forces due to the body or current can be detected. How to use magnetic field in a sentence.
Real-time measurement of the magnetic field in an experimental region of space is not always practical or feasible. In most cases, the experimental region is not accessible due to a physical enclosure (e.g., a setup placed in a vacuum chamber), or it could be that placing a magnetic ...
Although the mechanisms involved in the origination of magnetic fields in space are still uncertain, one of the widely accepted plausible scenarios is the turbulent dynamo, which amplifies the weak magnetic field35,36,37. Recent numerical studies and experiments with long pulse laser-produced colliding...
For example, when the first astronauts returned to earth sick, NASA concluded that their illness resulted from the lack of a planetary magnetic field in outer space. To resolve the problem, NASA placed magnets in the astronauts’ space suits and space travel vehicles, and astronauts have ...
In a uniform magnetic field of 10^(-5) T in free space, the energy density is u. The electric field which will produce the same energy density in free space
LOS ANGELES, May 21 (Xinhua) -- Jupiter's internal magnetic field is changing over time, a phenomenon observed by the U.S. National Aeronautics and Space Administration (NASA) for the first time outside of the Earth, the agency has said. ...
16. Objective:To approach the immunity status of pulse magnetic field treatment on treating Paediatric Lobular Pneumonia. 目的:探讨脉冲磁疗治疗小儿支气管肺炎前后体液免疫功能状况。 17. Pulse magnetic field treatment on treating Paediatric Lobular Pneumonia improve immunity function, boost up resistance of ...
(where μ0 is the magnetic permeability of free space). Combining this with Gauss' law for magnetism yields the result that the magnetic scalar potential is the solution to Laplace's equation: ∇·B→=0⇒∇2V=0. Ignoring any external field sources, the potential can be written in sph...
parallel alignment, while AM = − 1 represents a perpendicular alignment. The values of the AM are illustrated by chromatically superimposing the values onto the magnetic-field vectors as inferred from polarization measurements and are shown in Figs.1and2, as well as Supplementary Fig.1....
