"So basically your belt is a magnet and the sensor tag measures magnetic fields.
It even has a decibel meter to measure volume, and a teslameter, which measures magnetic fields.
In contrast, MEG measures magnetic fields, which does not use a reference, and MEG provides superior spatial resolution and signal-to-noise ratio relative to EEG.
It took 20 pictures of the planet as it flew past and had sensors to measure magnetic fields.
Later, Dr. Babcock invented a device to measure magnetic fields in stars and created a "seeing monitor" to evaluate mountaintops as potential homes for telescopes.
Physicists had earlier used X-rays to probe materials, but neutron scattering was the first technique able to detect the position of hydrogen atoms and to measure magnetic fields around atoms.
Using radar and ground-penetrating sensors, researchers from the University of Georgia were able to measure magnetic fields and and map the settlement that had once been called Santa Elena, the capital of Spanish Florida.
Suggested uses for superconducting materials include medical magnetic-imaging devices, magnetic energy-storage systems, motors, generators, transformers, computer parts, and very sensitive devices for measuring magnetic fields, voltages, or currents.
Instruments that measure magnetic fields are not new, said Dr. Dmitry Budker, a physics professor at the University of California, Berkeley, and an editor of "Optical Magnetometry," a coming book.
I made a device within a Helmholtz coil to measure magnetic fields with lasers, I researched concert hall acoustics, and having found some Russian doctoral work on the internet, I studied the drag coefficients of parachutes, filming them falling through clouds of smoke to observe the aerodynamics.
Messenger will operate behind a ceramic heat shield to keep its instruments at room temperature, and will pass only briefly over the hotter equatorial regions in order to limit exposure to heat reflected from the surface of the planet.The scientific equipment on board includes an instrument for measuring magnetic fields, and a battery of spectrometers for probing the chemistry of the planet.
