A new magnetic field detector has been formed by scientists which is almost 1000 times more efficient than all the existing magnetic field detectors. These new magnetic field detectors are made up of synthetic diamonds along with nitrogen vacancies (NVs), which makes them extremely sensitive to magnetic fields reception.
The devices which are used currently to detect magnetic fields are based on gas filled chambers which are made in such a way that they only work in narrow frequency bands, reports Omni Feed.
The nitrogen vacancies can be made to store in a diamond chip which is as small as a thumbnail. Around a trillion nitrogen vacancies can be stored in such a manner; and each of these vacancies have their own high magnetic field reception; thus making a very good receptor. But only this arrangement does not give a measurement of the magnetic field which has been recorded. The scientists then have to zap out the measurement and the reading from these nitrogen vacancies with the help of a laser light. Then, the laser light's intensity will tell them the intensity of the magnetic field.
But what is a nitrogen vacancy? It is nothing but a missing atom in a crystal. The electrons which are present in this vacancy has the ability to interfere and interact with magnetic fields and sense them accurately.
This device can be used to make very tiny and minuscule sized batteries and many huge devices can be powered by these powerful but small sized batteries. This can also find a great usage in contraband detection, medical imaging, and also in geological exploration. Scientists are still exploring options to make the use of this innovative device in the most useful way.
