Tiny Magnetometers Detect Fields Generated by Human Heart

The devices, about 1cm3 in size, were taken to the Physikalisch Technische Bundesanstalt (PTB) in Berlin, Germany where supposedly resides the most magnetically isolated building in the world. Using the tiny magnetometers, investigators were able to detect the magnetic signature of human heartbeats, perhaps opening up the possibility for a new modality to complement ECG.

As HAARP’s website comes back some Magnetometer data has gone missing

All we do know now is that HAARP public data between April 7 to April 12 is all removed and there is no press release yet or any reasonable explanation as to why. HAARP is definitely bouncing sounds off the Ionosphere which can cause magnetic disturbances as these people are playing around with stuff that can cause consequences. This isn’t the first time HAARP records and data has been removed. HAARP data right around the time of the Haiti earthquake has also been removed with no explanation as to why.

Liquid Hot Magma Ocean Resolved in Galileo Magnetometer Data

The magnetometer measured the absolute magnitude of the magnetic field surrounding the spacecraft and its magnitude in the three spatial components (Bx, By, and Bz). Near Io, the spacecraft mostly measured how Jupiter’s magnetic field was perturbed by Io’s atmosphere. In the atmosphere, plasma from Jupiter’s magnetosphere is slowed as it takes on more mass and as charge is exchanged with these new particles.


Premier has contracted Fugro Airborne Surveys to fly it’s HM1 high resolution magnetometer system along some 530 line-kilometres of flight lines. The survey, flown at a 50-metre line spacing, will provide critical information relating to the Northern Banded Iron Formation (NBIF) and any potential faults and shear zones which may transect it.

Suspended dIdD for Observatories

The Suspended dIdD simplifies the set-up of magnetic observatory installations by eliminating the need for fluxgate magnetometers and thermal insulating structures. In addition, the new system minimizes ongoing system calibrations,
which, in turn, frees personnel to concentrate on more essential tasks such as interpreting and understanding data.
