Magnetic encephalography (MEG) is a non-invasive imaging technique that can detect the tiny magnetic fields generated by electricity produced by the brain's neuronal activity. This method allows researchers to study brain function in real-time with high temporal resolution. This requires a well shielded environment.

The Mark I Magnaprobe's is a simple analog detector capable of responding to magnetic fields as weak as 0.3 gauss. This can prove invaluable in confirm the integrity of magnetically shielded rooms.

Magnetic encephalography (aka magnetoencephalography) can detect temporal and spatial information in the brain's magnetic signature when properly shielded from background magnetic fields. The brain's intrinsic electrical activity produces an extremely weak biomagnetic signal which can be measured by magnetically shielded equipment.

MEG research is directed toward brain functions such as perception, motor control, language, and cognition. In clinical applications in can map brain areas prior to surgery. This is particularly useful in treating epilepsy by localizing seizure sources.

I have bought several of these over the years, originally from the British company that makes them, and more recently from this company. I have trouble keeping them because everyone seems to want one. They are indispensable for showing the angle of the magnetic field in three dimensions. It is like a 3 dimensional compass, and very sensitive too. It will even show the vertical angle of the Earth's magnetic field! If your business is magnets, you need one of these.

Thanks for the feedback. This version, the Mark I is incredibly sensitive as you noted. We had them tested once & the will respond to a field as weak as 0.3 gauss. Besides declination they are great for detecting magnetic leakage in NMR/MRI labs. Overkill for Q/A though, use the Mark II instead.
