The present state of realization, maintenance and dissemination the quantity "magnetic flux density" in SI units is discussed. Different measuring methods that are in use for the calibration of field coils and permanent or electromagnetic systems in the flux density range from the order of the ...
At the typical frequency of 3 MHz the EM field penetrates into the thin skin layer of 1.3 mm in solid Si, 0.27 mm in molten Si, and 0.04 mm into the Ag inductor. The rest of the conducting bodies are free from the EM field. Using Maxwell's equations in quasi-static approximation, ...
The units of B and H in SI unit system are T and A/m, respectively. Magnetic field intensity inside an object with magnetization M is B = μ0(M + H). Substitution of expression for M makes B = μH, where μ = μ0(1 +χ) is the magnetic permeability of matter. The entire ...
The applied magnetic field is shown in reduced units relative to the critical field Bc in Fig. 1f, in order to facilitate a comparison between the results obtained with and without demagnetizing fields. In both cases, Bc is the phase-transition field between conical and saturated ferromagnetic ...
Here, |si〉 are the field-dependent spin eigenstates determined from Eq. (3), and pμ are the normalized selection rules between the singlet and the corresponding symmetrized basis states |sμ〉. This formulation corresponds to the usual assumption that the ISC transitions are incoherent, i.e...
Here, we recognized the importance of mantle electrical conductivity and developed a simple yet effective model that allows us to connect the geomagnetic field at the Earth’s surface to that on the CMB. As stated above, the Earth’s mantle has nonzero electrical conductivity [1,2,3], a ...

3D Magnetic Field Sensor Concept for Use in Inertial Measurement Units (IMUs). We report on the design, fabrication, and characterization of a microfabricated 3D magnetic field sensor that is suitable for co-integration with inertial ... Ettelt,Dirk,Rey,... - 《Journal of Microelectromechanical...
Using data from Ørsted, CHAMP and geomagnetic observatories, the British Geological Survey is deriving models of the Earth's magnetic field at least every year to gain a better understanding of the different magnetic field sources and to support various navigational applications. Research highlights ...
field generated by the 800-p.p.m.29Si nuclei, and that the amount of this drift increases at lower magnetic field. The field dependence indicates that the hyperfine field drift is mostly driven by the ESR signal used to measure it, a finding that informs critical engineering trade-offs in...
