Magnetic Hysteresis at Low Flux Densities
Physics, 1935The energy loss per cycle in a ferromagnetic material subjected to small alternating fields is sometimes separated into three parts; the first due to eddy current loss, the second to hysteresis presumed to follow Rayleigh's laws at these flux densities. The origin of the remainder is unknown and is the subject of much controversy; it has been variously

Anti-counterfeiting Using Irregularities of Magnetic Flux Density
2015 IEEE International Conference on Computer and Information Technology; Ubiquitous Computing and Communications; Dependable, Autonomic and Secure Computing; Pervasive Intelligence and Computing, 2015In recent years, many studies have used physical unclonable functions (PUFs), which are difficult to reproduce and highly secure, as a means to discriminate between counterfeit and authentic goods. Magnetic materials are widely used in items ranging from everyday goods to medical equipment and may be good PUF candidates given their versatility compared

Current and Magnetic Flux Density
2013We know that there exists a force between currents. This phenomenon is similar to the Coulomb force between electric charges. Hence, we can presume that currents also make some field in space similar to the electric field made by electric charges. This field is called the magnetic field.

Cytogenetic effects of 50 Hz magnetic fields of different magnetic flux densities
Bioelectromagnetics, 2000Cytogenetic investigations were performed in human peripheral blood lymphocytes following exposure to 50 Hz magnetic fields alone or in combination with the chemical mutagen mitomycin C or with X-rays. It was found that magnetic fields up to 2500 microT did not significantly influence the chromosome aberration and sister chromatid exchange frequency ...

The Definitions of Magnetic Flux Density and Field Intensity
American Journal of Physics, 1953The present theory of magnetism, in which it is treated as a phenomenon of current electricity, suffers from objections which are pointed out. The meanings of B and H on an atomic scale are considered, and a method of picturing B and H, inside a ferromagnetic body, without mentioning magnetic poles or dipoles, is developed. It is shown that this method

Spherical magnetic flux density sensor array
In the field of medical imaging, particularly magnetic particle imaging, the accurate measurement of magnetic fields in field generators is of significant importance for the assessment of implementation quality and the detection of deviations by the used material and manufacturing tolerances.Aderhold, Eric +7 more
