Definitions for magnetic field
This page provides all possible meanings and translations of the word magnetic field
magnetic field, magnetic flux, flux(noun)
the lines of force surrounding a permanent magnet or a moving charged particle
a condition in the space around a magnet or electric current in which there is a detectable magnetic force and two magnetic poles are present
A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude; as such it is a vector field. The magnetic field is most commonly defined in terms of the Lorentz force it exerts on moving electric charges. Magnetic field can refer to two separate but closely related fields which are denoted by the symbols B and H. Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin. In special relativity, electric and magnetic fields are two interrelated aspects of a single object, called the electromagnetic tensor; the split of this tensor into electric and magnetic fields depends on the relative velocity of the observer and charge. In quantum physics, the electromagnetic field is quantized and electromagnetic interactions result from the exchange of photons. In everyday life, magnetic fields are most often encountered as an invisible force created by permanent magnets which pulls on iron objects and attracts or repels other magnets. Magnetic fields are very widely used throughout modern technology, particularly in electrical engineering and electromechanics. The Earth produces its own magnetic field, which is important in navigation. Rotating magnetic fields are utilized in both electric motors and generators. Magnetic forces give information about the charge carriers in a material through the Hall effect. The interaction of magnetic fields in electric devices such as transformers is studied in the discipline of magnetic circuits.
Is the magnetic effect of electric currents and magnetic material at a given point is specified by both a direction and a magnitude.
Magnetic fields are widely used in modern technology, particularly in electrical engineering and electromechanics. The Earth produces its own magnetic field, which is important in navigation, and it plays a role in the integration of the solar wind.
Sample Sentences & Example Usage
That could be particularly interesting, because whether or not a planet has a magnetic field may be an important factor in habitability.
Most of the headphones that you see in the market use cone drivers. What we do is use a type of driver called a planar driver, it's a very small, thin transducer placed in a magnetic field which then produces sound.
In our paper, we have shown that a super Carrington-type CME event would have greatly compressed the magnetic field, this would ignite huge electric currents on Earth and let energetic particles penetrate the Earth’s atmosphere and surface.
For shocks traveling toward our planet, Earth ’s magnetic field would take the direct hit such that most of the resulting disturbance would be confined to Earth ’s outer magnetic field – our magnetosphere – with the ‘ noticeable ’ effects being those associated with a large geomagnetic storm – bright aurora, communications disturbances, scattered electrical power outages.
I was always brainstorming how we could use a telescope in other ways, is there a way you could use a telescope to look inside a planetary body? Then I thought, the aurorae! Because aurorae are controlled by the magnetic field, if you observe the aurorae in an appropriate way, you learn something about the magnetic field. If you know the magnetic field, then you know something about the moon's interior.
