Sentences with phrase «very small magnetic fields»

This sensitivity enables the NV - magnetoscope to detect very small magnetic fields — such as that produced by nano - and mesoscale magnetic materials, for example — by reading optical fluorescence emitted by the excited NV centers.

But they also found that even very small magnetic fields were enough to prevent thermal fluctuations from flipping electron spins.

These sensors can measure very small magnetic fields, enabling Wheeler to place the magnet and sensor farther from each other than was previously possible.

After sweeping a very small magnetic field over the setup, the researchers found the Majorana particles» distinct quantized signal — the telltale fingerprint of a specific type of quantum particles — in the electrical traffic between the two materials.

Not exact matches

And Hall probes can be used to measure very small and slow fluctuations in a magnetic field, down to a hundredth of a gauss (the unit of measurement for magnetic field strength, named for mathematician Carl Friedrich Gauss).

Firstly, as the magnetic field does not allow very large molecular clouds to collapse and form stars, star formation can occur only after the clouds break up into smaller clouds.

«Aurora [s] are very unlikely because (a) it's very unlikely there's a magnetic field to focus the charged particles into a small region of the atmosphere (necessary at other planets) and (b) the tenuous solar wind is likely deflected far [10s of Pluto radii] around Pluto,» Bagenal said in an email.

Gennady Fiksel, of the University of Rochester, and William Fox continued their previous research by adding a magnetic field by pulsing current through very small wires.

STAFF is capable of detecting rapid variations in magnetic fields, which means that very small spatial structures can be recognised within the plasma.

Large changes in cosmic rays are documented in response to magnetic - field variations (the Laschamp event of about 40,000 years ago is especially prominent) with no corresponding change in climate, so any cosmic - ray influence on the climate must be very small (a weak correlation can be obscured by noise; a strong control is almost always visible «by eye,» and clearly is absent).

[Response: In this estimation, you divided a small amplitude ba an even smaller (the 22 - year Hale cycle is not very strong, and not even discernable in the sunspot record, even though we have reasons to believe it exists since the magnetic fields flip), thus not a very reliable method.

I agree that these numbers are not a correct measure, but even so they tell that any effect on the Sun or the Earth is very small, and that Saturn, in particular, is already so distant that neither its mass nor its magnetic fields can have much influence on anything in the Sun or for the Earth.

But we're approaching to the stage when the magnetic field of the sun is going to be very, very small.
