When a material is magnetized ( for example, by placing it in an external magnetic field ), the electrons remain bound to their respective atoms, but behave as if they were orbiting the nucleus in a particular direction, creating a microscopic current.

When the currents from all these atoms are put together, they create the same effect as a macroscopic current, circulating perpetually around the magnetized object.

When the ferromagnetic material is magnetized, it biases the amorphous metal strip into saturation, where it no longer produces harmonics.

When a player is decapitated, his head is immediately magnetized and used as the rok, as the original rok ( or, sometimes, previous head ) vanishes.

When ferromagnetic material is placed within a magnetic field, the magnetic dipoles align to the applied field, thus expanding the domain walls of the magnetic domains.

A superparamagnetic system will show a characteristic frequency dependence: When the frequency is much higher than 1 / τ < sub > N </ sub >, there will be a different magnetic response than when the frequency is much lower than 1 / τ < sub > N </ sub >, since in the latter case, but not the former, the ferromagnetic clusters will have time to respond to the field by flipping their magnetization.

When the spins interact with each other in such a way that the spins align spontaneously, the materials are called ferromagnetic ( what is often loosely termed as magnetic ).

When a magnetic field higher than the ferromagnetic limit of 1. 6 T is needed, superconducting electromagnets can be used.

When the magnetic field through a piece of ferromagnetic material like iron is changing, the magnetization of the material changes in a series of tiny discontinuous jumps, which can be heard as a series of clicks in a loudspeaker attached to a coil of wire around the iron.

When a mineral such as magnetite cools below the Curie temperature, it becomes ferromagnetic but is not immediately capable of carrying a remanence.

When combined with the metaphysical notion that pure forms of this universe are best appreciated when least embodied in a material substratum, it becomes clear that while earth will be dross on a scale of material-formal ratios, celestial bodies will be of a subtle, quickened, ethereal existence, in whose embodiment pure form will be the dominant component and matter will be absent or remain subsidiary.

When he heard that Paul Whiteman was looking for singers to replace the Rhythm Boys, Mercer applied and got the job, `` not for my voice, I'm sure, but because I could write songs and material generally ''.

When the writer uses material does he tamper with it to improve its commercial effect or does he leave it pure??

When the light from a heated material was passed through a prism, it produced a multi-colored spectrum.

When the Western Roman Empire was starting to disintegrate, Augustine developed the concept of the Catholic Church as a spiritual City of God ( in a book of the same name ), distinct from the material Earthly City.

The Irish anti-war song " Johnny I Hardly Knew Ye " and " When Johnny Comes Marching Home " share the same melodic material.

When reconstructing the data, owing to the evaporation of successive layers of material from the sample, the lateral and in-depth reconstruction values are highly anisotropic.

When a symbol is not marked by any of the three grammar symbols ( square, cone, inverted cone ), they may be a non material thing, a grammatical particle, etc.

When the working liquid is water and the bain-marie is used at sea level, the maximum temperature of the material in the lower container will not exceed 100 degrees Celsius ( 212 F ), the boiling point of water at sea level.

When BSE material infects humans, the resulting disease is known as ( new ) variant CJD ( nvCJD ).

When the Church chooses to canonize new material, it is typically added to the Doctrine and Covenants ; the most recent changes were made in 1981.

When scientists transfer a gene from one cell into another cell in order to express the new genetic material as a protein in the recipient cell, the cDNA will be added to the recipient ( rather than the entire gene ), because the DNA for an entire gene may include DNA that does not code for the protein or that interrupts the coding sequence of the protein ( e. g., introns ).

When a small increment of heat is gained by a calorimetric body, with small increments, of its volume, and of its temperature, the increment of heat,, gained by the body of calorimetric material, is given by

When the magma approaches the surface of the Earth, the rapid off-loading of overlying material causes the trapped gases to decompress rapidly, thus triggering explosive destruction of the magma and spreading volcanic ash over wide areas.

When Yellowstone Caldera last erupted some 650, 000 years ago, it released about 1, 000 km < sup > 3 </ sup > of material ( as measured in dense rock equivalent ( DRE )), covering a substantial part of North America in up to two metres of debris.

When the business failed, his father would quietly turn the huge stacks of useless stationery and pencils over to his children, requiring them to use up all the material as fast as possible.

When all of the sound, picture, and data elements of a production have been completed, they may be assembled into a Digital Cinema Distribution Master ( DCDM ) which contains all of the digital material needed for projection.

When EM radiation at the frequences for which it is referred to as " radio waves " impinges upon a conductor, it couples to the conductor, travels along it, and induces an electric current on the surface of the conductor by moving the electrons of the conducting material in correlated bunches of charge.

When matter ( ordinary material particles ) is changed into energy ( such as energy of motion, or into radiation ), the mass of the system does not change through the transformation process.

When unfamiliar material ( not from their domain of expertise ) is presented to experts, their recall is no better than that of novices.

When he arrived home, Sullivan learned he would not be able to air the Bergman material from it.

" When deactivation occurs, the student has an understanding of the material and is able to retain information.

When this material condenses in the rain, it forms dust and light sandy materials that resembles ground pumice.

When applied to whiteware ceramics, vitreous means the material has an extremely low permeability to liquids, often but not always water, when determined by a specified test regime.

When light strikes a material, most of the light is absorbed while a smaller amount of a particular frequency or wavelength is reflected.
