Ferromagnetic in a sentence

Ferromagnetic core inductor A variety of types of ferrite core inductors and transformers Ferromagnetic-core or iron-core inductors use a magnetic core made of a ferromagnetic or ferrimagnetic material such as iron or ferrite to increase the inductance.

Air core coils have lower inductance than ferromagnetic core coils, but are often used at high frequencies because they are free from energy losses called core losses that occur in ferromagnetic cores, which increase with frequency.

Ferromagnetic materials seeAlso The table on the right lists a selection of ferromagnetic and ferrimagnetic compounds, along with the temperature above which they cease to exhibit spontaneous magnetization (see Curie temperature ).

First reported in the case of a ferromagnetic to anti-ferromagnetic transition, citation such persistent phase coexistence has now been reported across a variety of first-order magnetic transitions.

The thought of using coilgun systems that fire relatively light, ferromagnetic slugs is also floated in the 2012 paper, but sulfur-adapted systems don’t yet exist.

First the team investigated how angle θ between ferromagnetic layer magnetizations depends on angle φ between the axes of the antiferromagnets (fig. 1a, top).

The Ferromagnetic Detection System Market report contains an analysis of the major factors influencing the growth of the market (drivers, restraints, opportunities, and challenges).

An example of such behavior is the 3D ferromagnetic phase transition.

By adding a " magnetic core " made of a ferromagnetic material like iron inside the coil, the magnetizing field from the coil will induce magnetization in the material, increasing the magnetic flux.

Compass correction main A binnacle containing a ship's standard compass, with the two iron balls which correct the effects of ferromagnetic materials.

Ferromagnetic core inductors driven into saturation can also be used at lower frequencies.

Flexible magnets are composed of a high- coercivity ferromagnetic compound (usually ferric oxide ) mixed with a plastic binder. citation This is extruded as a sheet and passed over a line of powerful cylindrical permanent magnets.

For example, impurities in semiconducting ferromagnetic alloys lead to different properties, as first predicted by White, Hogan, Suhl, Tian Abrie and Nakamura. citation citation Some alloys are made by melting and mixing two or more metals.

Gadolinium becomes ferromagnetic at below 16 °C (Curie point).

Gadolinium is paramagnetic at room temperature, with a ferromagnetic Curie point of 20 °C. citation Paramagnetic ions, such as gadolinium, enhance nuclear relaxation rates.

However, if it is wrapped around a soft ferromagnetic material, such as an iron nail, then the net field produced can result in a several hundred- to thousandfold increase of field strength.

If all the dipoles in a piece of ferromagnetic material are aligned parallel, it creates a large magnetic field extending into the space around it.

If one subband is preferentially filled over the other, one can have itinerant ferromagnetic order.

Inductors with ferromagnetic cores have additional energy losses due to hysteresis and eddy currents in the core, which increase with frequency.

Inductors wound around a ferromagnetic core may saturate at high currents, causing a dramatic decrease in inductance (and Q).
