Sentences with phrase «even smallest magnetic fields»

With the help of the electrons of the resulting nitrogen vacancy center, even smallest magnetic fields can be detected with a resolution of a few nanometers thanks to nuclear magnetic resonance (NMR) spectroscopy.

«Our magnetometers (magnetic field sensors) are highly sensitive and can reliably measure even the smallest of changes in the ambient magnetic field,» explains Professor Uwe Hartmann.

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

The smaller star is the source of the magnetic field, and even though that field is about 1000 times stronger than the sun's, imaging it still required two arrays of radiotelescopes, plus two extra dishes, to detect the signals generated by magnetic fields.

[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.
