When a beam of silver atoms was passed through a specially shaped magnetic field, the beam was split based on the direction of an atom's angular momentum, or spin.

When placed in an electric or magnetic field, equal but opposite forces arise on each side of the dipole creating a torque τ:

When the current changes, the magnetic field does too, inducing a voltage between the ends of the conductor.

When these tiny magnetic dipoles are aligned in the same direction, their individual magnetic fields add together to create a measurable macroscopic field.

When combined with yttrium, it forms highly magnetic compounds.

When a magnetic field is present that is not parallel to the direction of motion of moving charges, these charges experience a force, called the Lorentz force.

When such a magnetic field is absent, the charges follow approximately straight, ' line of sight ' paths between collisions with impurities, phonons, etc.

When a current-carrying semiconductor is kept in a magnetic field, the charge carriers of the semiconductor experience a force in a direction perpendicular to both the magnetic field and the current.

When electrons flow through a conductor, a magnetic field is produced.

When the current flowing through an inductor changes, creating a time-varying magnetic field inside the coil, a voltage is induced, according to Faraday's law of electromagnetic induction, which by Lenz's law opposes the change in current that created it.

When a magnetic field is applied, the molecules will tend to align with or against the field.

When a person is inside the powerful magnetic field of the scanner, the average magnetic moment of many protons becomes aligned with the direction of the field.

: When a material is put in a magnetic field, the electrons circling the nucleus will experience, in addition to their Coulomb attraction to the nucleus, a Lorentz force from the magnetic field.

When an external magnetic field is applied, these magnetic moments will tend to align themselves in the same direction as the applied field, thus reinforcing it.

When exposed to a magnetic field, the domain boundaries move so that the domains aligned with the magnetic field grow and dominate the structure as shown at the left.

When a magnetized ferromagnetic material is heated to the Curie point temperature, the molecules are agitated to the point that the magnetic domains lose the organization and the magnetic properties they cause cease.

When a ferromagnet or ferrimagnet is sufficiently small, it acts like a single magnetic spin that is subject to Brownian motion.

When a charged particle moves through a magnetic field B, it feels a Lorentz force F given by the cross product:

When in December 1978 there was media speculation that Prince Charles might marry a Roman Catholic, Powell defended the provision that excludes Roman Catholics from ascending the throne, claiming his objection was not rooted in religious bigotry but in political considerations.

When the deadline came, Australian media baron Rupert Murdoch was negotiating to buy the paper and save it.

When a field travels across to different media, the properties of the field change according to the various boundary conditions.

When they released the orbit of Sputnik to the media, the Russians were dumbfounded to learn how powerful American computers had become, as they would not have been able to calculate the orbit themselves.

When the term was introduced to wider society by the mainstream media in 1983, even those in the computer community referred to computer intrusion as " hacking ", although not as the exclusive use of that word.

According to Hideo Tokuoka, " When Americans think of incest, they think of fathers and daughters ; in Japan one thinks of mothers and sons " due to the extensive media coverage of mother-son incest there.

When he declared to the House of Commons in November 1993 that " to sit down and talk with Mr. Adams and the Provisional IRA ... would turn my stomach ", Sinn Féin gave the media an outline of the secret talks indeed held regularly since that February.

When a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency remains constant.

When news customers share common beliefs, profit-maximizing media outlets find it optimal to select and / or frame stories in order to pander to those beliefs.

Likewise, Richard McNally states, " The term ' pseudoscience ' has become little more than an inflammatory buzzword for quickly dismissing one's opponents in media sound-bites " and " When therapeutic entrepreneurs make claims on behalf of their interventions, we should not waste our time trying to determine whether their interventions qualify as pseudoscientific.

When the water in paint media touches parchment's surface, the collagen melts slightly, forming a raised bed for the paint, a quality highly prized by some artists.

When the interview was published, a media firestorm emerged, and the band found themselves under intense scrutiny.

When it becomes possible for a people to describe as ‘ postmodern ’ the décor of a room, the design of a building, the diegesis of a film, the construction of a record, or a ‘ scratch ’ video, a television commercial, or an arts documentary, or the ‘ intertextual ’ relations between them, the layout of a page in a fashion magazine or critical journal, an anti-teleological tendency within epistemology, the attack on the ‘ metaphysics of presence ’, a general attenuation of feeling, the collective chagrin and morbid projections of a post-War generation of baby boomers confronting disillusioned middle-age, the ‘ predicament ’ of reflexivity, a group of rhetorical tropes, a proliferation of surfaces, a new phase in commodity fetishism, a fascination for images, codes and styles, a process of cultural, political or existential fragmentation and / or crisis, the ‘ de-centring ’ of the subject, an ‘ incredulity towards metanarratives ’, the replacement of unitary power axes by a plurality of power / discourse formations, the ‘ implosion of meaning ’, the collapse of cultural hierarchies, the dread engendered by the threat of nuclear self-destruction, the decline of the university, the functioning and effects of the new miniaturised technologies, broad societal and economic shifts into a ‘ media ’, ‘ consumer ’ or ‘ multinational ’ phase, a sense ( depending on who you read ) of ‘ placelessness ’ or the abandonment of placelessness (‘ critical regionalism ’) or ( even ) a generalised substitution of spatial for temporal coordinates-when it becomes possible to describe all these things as ‘ Postmodern ’ ( or more simply using a current abbreviation as ‘ post ’ or ‘ very post ’) then it ’ s clear we are in the presence of a buzzword.

'" When describing his views of the peace process among Arab leaders and in the media of the Arab world, Arafat's rhetoric became noticeably more bellicose than it was when among Western leaders and media outside of the Arab world.

: When sent from client to server, ANNOUNCE posts the description of a presentation or media object identified by the request URL to a server.

When a Cabinet reshuffle is imminent, a lot of time is taken up in the conversations of politicians and in the news media, speculating on who will, or will not, be moved in and out of the Cabinet by the Prime Minister, because the appointment of ministers to the Cabinet, and threat of dismissal from the Cabinet, is the single most powerful constitutional power which a Prime Minister has in the political control of the Government in the Westminster system.

When the proposal was released to the media on 25 August, it was met with mixed reception.

When light encounters a boundary between two media with different refractive indices, some of it is usually reflected as shown in the figure above.

When two devices, that are both DTE or both DCE, must be connected together without a modem or a similar media translator between them, a crossover cable must be used, e. g. a null modem for RS-232 or an Ethernet crossover cable.

When the light or other wave involved is monochromatic, that is, of a single frequency, Snell's law can also be expressed in terms of a ratio of wavelengths in the two media, λ < sub > 1 </ sub > and λ < sub > 2 </ sub >:

When connecting glassware, it is often tempting to use Keck clips on every joint, but this can be dangerous if the system is sealed or the exhaust is in any way restricted ; e. g. by wash flasks or drying media.

When these results were first reported in 2002, the popular media sensationalized the story and exaggerated the risk, while the manufacturer continued to attempt to minimize the degree of risk.
