a测量磁场时将发射线圈及传感器架高,安放到基点或钢管正上方,传感器到地 Surveys when the magnetic field the transmitting coil and the sensor will elevate, place to the basic point or the steel pipe place above, the sensor will arrive[translate] ...
It's possible to calculate or estimate the largest reasonable magnetic field such a device might produce, but the smallest (to be able to ensure detection) is impossible. All it takes is a few pieces of iron to concentrate the field into a smaller space, and your sensible external field go...

Large gap magnetic suspension system with superconducting coils A magnetic suspension system and a procedure for operating the system employ a superconducting magnet having a lift coil assembly for developing a magnetic field to interact with the magnetic field of an object to be supported about the ...
(based on pure tissue samplings and slice position), to correct for anteroposterior drift in signal intensity values due to magnetic field inhomogeneities, head coil artifact, and subject-induced distortions; (3) the windowing threshold value for the gray vs white tissue compartments was defined as...
High resolution imaging of biomagnetic fields generated by action currents in cardiac tissue using a LTS-SQUID microscope For a 500 μm diameter pickup coil we achieved a field sensitivity of 330 fT Hz 1/2 for frequencies above 1 Hz. This allows us to record magneto... F Baudenbacher,NT...
The device, which is able to measure magnetic moments in excess of 1 A m2(1000 emu), is validated by (i) a direct calibration experiment using a small coil driven by a known current and (ii) by comparison with the results of numerical calculations obtained previously using a flux ...
A magnetic resonance imaging receiving coil (10) having an improved signal-to-noise ratio comprising two or more separate quadrature volume coils (12, 14), each intercepting the two quadrature components of the magnetic resonance signal within its own sensitive volume, and the two or more quadratu...
