MEG measures magnetic fields resulting from cortical activity.

However, this effect is very weak, because the magnetic fields generated by individual spins are small and the resulting alignment is easily destroyed by thermal fluctuations.

Functional magnetic resonance imaging has revealed that, after losing a bet or gamble (" riskloss "), the frontoparietal network of the brain is activated, resulting in more risk-taking behavior.

If they did exist, both Gauss's law for magnetism and Faraday's law would need to be modified, and the resulting four equations would be fully symmetric under the interchange of electric and magnetic fields ; see magnetic monopoles for details.

In pure paramagnetism, the dipoles do not interact with one another and are randomly oriented in the absence of an external field due to thermal agitation, resulting in zero net magnetic moment.

When a magnetic field is applied, the dipoles will tend to align with the applied field, resulting in a net magnetic moment in the direction of the applied field.

If there is sufficient energy exchange between neighbouring dipoles they will interact, and may spontaneously align or anti-align and form magnetic domains, resulting in ferromagnetism ( permanent magnets ) or antiferromagnetism, respectively.

It has been experimentally demonstrated that, as a consequence, when the magnetic field is increased beyond the critical field, the resulting phase transition leads to a decrease in the temperature of the superconducting material.

In a perfect conductor, an arbitrarily large current can be induced, and the resulting magnetic field exactly cancels the applied field.

The earliest magnetic recording systems simply applied the unadulterated ( baseband ) input signal to a recording head, resulting in recordings with poor low-frequency response and high distortion.

The particles are then propelled by the Lorentz force resulting from the interaction between the current flowing through the plasma and the magnetic field ( which is either externally applied, or induced by the current ) out through the exhaust chamber.

The coils of a mass-driver can induce eddy-currents in a payload's aluminum coil, and then act on the resulting magnetic field.

It uses radio waves to ionize and heat a propellant, and magnetic fields to accelerate the resulting plasma to generate thrust.

The resulting rapidly-changing electric fields and magnetic fields may couple with electrical / electronic systems to produce damaging current and voltage surges.

Although these weapons were much smaller ( 300 kiloton or 1. 3 PJ ) than the Starfish Prime test, since those tests were done over a populated large land mass ( and also at a location where the Earth's magnetic field was greater ), the damage caused by the resulting EMP was reportedly much greater than in the Starfish Prime nuclear test.

As a distributed ( or α < sup > 2 </ sup >) dynamo may become relevant, both the magnetic flux on the surface and the topology of the magnetic fields in the corona should systematically change across this transition, perhaps resulting in some discontinuities in the X-ray

This turns the magnetic particles at an angle to the ambient field, resulting in gyration.

The spin of these electrons can be aligned, resulting in very strong magnetic fields, and therefore, these elements are used in compact high-strength magnets where their higher price is not a concern.

The Earth is cooling, and the resulting heat flow generates the Earth's magnetic field through the geodynamo and plate tectonics through mantle convection.

*** Synchronous motor, an alternating current motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it

with g < sub > S </ sub > the electron-spin g-factor ( about 2 ), resulting in a total magnetic moment, μ,

The deposit of rupees to the account of the Government of the United States of America in payment for the commodities and for ocean transportation costs financed by the Government of the United States of America ( except excess costs resulting from the requirement that United States flag vessels be used ) shall be made at the rate of exchange for United States dollars generally applicable to import transactions ( excluding imports granted a preferential rate ) in effect on the dates of dollar disbursement by United States banks, or by the Government of the United States of America, as provided in the purchase authorizations.

The unsatisfactory 1958-60 expansion, he said, was not due to inadequate growth forces inherent in our economy but rather to the adverse effect of inappropriate economic policies combined with retrenching decisions resulting from the steel strike.

In addition, serum levels of doxycycline and erythromycin succinate two bacteriostatic antibacterials ( see above ) may be reduced by alcohol consumption, resulting in reduced efficacy and diminished pharmacotherapeutic effect.

When large numbers of delayed signals are mixed over several seconds, the resulting sound has the effect of being presented in a large room, and it is more commonly called reverberation or reverb for short.

The butterfly effect is a common trope in fiction when presenting scenarios involving time travel and with hypotheses where one storyline diverges at the moment of a seemingly minor event resulting in two significantly different outcomes.

Benzodiazepines enhance the effect of the neurotransmitter gamma-aminobutyric acid ( GABA-A ), resulting in sedative, hypnotic ( sleep-inducing ), anxiolytic ( anti-anxiety ), anticonvulsant, and muscle relaxant properties ; also seen in the applied pharmacology of high doses of many shorter-acting benzodiazepines are amnesic-dissociative actions.

Whenever a relative atomic mass value differs by more than 1 % from a whole number, it is due to this averaging effect resulting from significant amounts of more than one isotope being naturally present in the sample of the element in question.

The members of this group are known as catnip or catmint because of their effect on cats — the nepetalactone contained in nepeta binds to the olfactory receptors of cats, typically resulting in temporary euphoria.

The Viking siege of Paris ( 885 – 6 A. D .) “ saw the employment by both sides of virtually every instrument of siege craft known to the classical world, including a variety of catapults ,” to little effect, resulting in failure.

In circumstances where a character does not have control of an event, such as when a trap or magical effect is triggered or a spell is cast, a saving throw can be used to determine whether the resulting damage is reduced or avoided.

Current gun manufacturers such as Caspian Arms make slide assemblies and small parts such as triggers and safeties for Colt M1911 pistols from powdered Swedish steel resulting in a swirling two-toned effect ; these parts are often referred to as " Stainless Damascus ".

Also, resulting greenhouse gas emissions, chiefly carbon dioxide, from the widespread use of engines in the modern industrialized world is contributing to the global greenhouse effect – a primary concern regarding global warming.

) Forth environments vary in how the resulting program is stored, but ideally running the program has the same effect as manually re-entering the source.

Teasdale and Owen ( 1989 ), for example, found the effect primarily reduced the number of low-end scores, resulting in an increased number of moderately high scores, with no increase in very high scores.

Oceanic-continental convergence resulting in subduction and volcanic arc s illustrates one effect of plate tectonics.

The braid pattern ensures that each wire strand spends the same amount of its length on the outside of the braid, so skin effect distributes the current equally between the strands, resulting in a larger cross-sectional conduction area than an equivalent single wire.

This effect is called ion channelling, and, like all the channelling effects, is highly nonlinear, with small variations from perfect orientation resulting in extreme differences in implantation depth.

Q is similar to N in its effect: Q binds to RNA polymerase in Qut sites and the resulting complex can ignore terminators, however the mechanism is very different ; the Q protein first associates with a DNA sequence rather than an mRNA sequence.

The drop in the national birth rate during and after the war, resulting from a national shortage of young men created an " echo " effect in the generation that provided the French conscript army in the mid-1930s.

Also, there is some evidence that methadone and other opioids may cause cardiac conduction problems ( prolonged QTc interval ) although there are few documented cases of fatalities resulting from this side effect with methadone.

In effect, all three incident beams interact ( essentially ) simultaneously to form several real-time holograms, resulting in a set of diffracted output waves that phase up as the " time-reversed " beam.

The smoke resulting would be largely opaque to solar radiation but transparent to infra-red, thus cooling by blocking sunlight but not causing warming from enhancing the greenhouse effect.

' A balance must be struck between the need on one side for the legal certainty resulting from the binding effect of previous decisions, and on the other side the avoidance of undue restriction on the proper development of the law ( 1966 Practice Statement ( Judicial Precedent ) by Lord Gardiner L. C.
