Flux in a sentence

The two principal types of flux are acid flux, used for metal mending and plumbing, and rosin flux, used in electronics, where the corrosiveness of acid flux and vapors released when solder is heated would risk damaging delicate circuitry.

In practice, some flux traverses paths that take it outside the windings. citation Such flux is termed leakage flux, and results in leakage inductance in series with the mutually coupled transformer windings.

Leakage flux of a transformer Leakage flux main The ideal transformer model assumes that all flux generated by the primary winding links all the turns of every winding, including itself.

Magnetic flux The magnetic flux density ( magnetic field ) having the unit Wb/m 2 ( Tesla ) is denoted by B, and magnetic flux is defined analogously: : with the same notation above.

Soldering flux will help to remove oxide; the more active the flux the better the cleaning, although acidic flux used on circuit boards and not carefully cleaned off will cause corrosion.

Also acts as a generalization of heat flux, which is equal to the radiative flux when restricted to the infrared spectrum.

As one fundamental limitation, any method which produces a neutron flux that is captured to heat a working fluid will also bombard its electrodes with that flux, heating them as well.

As will be made clear, the easiest way to relate the two concepts is that the surface integral of a flux according to the first definition is a flux according to the second definition.

Because of their symmetry, toroidal cores allow a minimum of the magnetic flux to escape outside the core (called leakage flux ), so they radiate less electromagnetic interference than other shapes.

By contrast, according to the second definition, flux is the integral over a surface; it makes no sense to integrate a second-definition flux for one would be integrating over a surface twice.

Confusingly, the Poynting vector is sometimes called the power flux, which is an example of the first usage of flux, above.

Conversely, one can consider the flux the more fundamental quantity and call the vector field the flux density.

Due to the conflicting definitions of flux, and the interchangeability of flux, flow, and current in nontechnical English, all of the terms used in this paragraph are sometimes used interchangeably and ambiguously.

Given a flux according to the second definition, the corresponding flux density, if that term is used, refers to its derivative along the surface that was integrated.

If an object has a certain magnetic flux over its surface area, and that area shrinks to a smaller area, but the magnetic flux is conserved, then the magnetic field would correspondingly increase.

If the heat flux experienced by an entry vehicle is insufficient to cause pyrolysis then the TPS material's conductivity could allow heat flux conduction into the TPS bondline material thus leading to TPS failure.

In contrast to using traditional bars or coiled wires of all-metal solder and manually applying flux to the parts being joined, much hand soldering since the mid-20th century has used flux-core solder.

One hypothesis is that of "flux freezing", or conservation of the original magnetic flux takes place during the formation of the neutron star.

Some of the plasma in a flux surface will be on the outside (larger major radius, or "low-field side") of the torus and will drift to other flux surfaces farther from the circular axis of the torus.

Spectral flux multiplied by wavelength or frequency, whose unit is W, i.e. the same as the integral quantity: : The area under a plot with logarithmic wavelength or frequency horizontal axis equals to the total radiant flux.
