The magnetometer detected the field created by the induced current, and software sorted out the signal to determine the distance to the pipe.
Many animals rely on the magnetic field for navigation, and researchers have often wondered if people, too, might be able to detect the field; that might explain how Polynesian navigators can make 3,000-mile 3,000-milender starless skies.
However, there are also probes that are designed to detect the field parallel to the surface, such as the work in [35].
These sets of results present significant findings: First, these results suggest that fLCI may be able to detect the "field effect" of carcinogenesis.
However, until now, these clinical devices have never worked at the quantum limit and so have not been sensitive enough to detect the fields from individual nerve fibers.
That's important because, at least in theory, it allows them to detect the fields associated with nerves at a distance of several millimeters.
With the implant, Rowlands found he could detect the fields surrounding microwaves, refrigerators and power converters.
A new sensor can detect the fields, report Gang Xiao and Ben Schrag of Brown University in Providence, Rhode Island.
The quasistatic EM fields used by Arumugam (so called because they aren't completely stationary) are actually emitted by devices on the people being tracked; receivers outside would detect the fields and be able to tell exactly where the devices were and even which direction they were facing.
A 2005 report from the World Health Organization -- Brundtland's former agency -- stated that people who believe they're sensitive to EMFs don't seem to have any special abilities to actually detect the fields.
