Magnetic flux flows of optical quasi binormal magnetic flows with flux density

Waves in Random and Complex Media, 2021
In this paper, we extract distinctive determination for quasi magnetic flux of the quasi binormal magnetic flows of magnetic quasi (Formula presented.) -particle by considering directional frame in 3D ordinary space. Also, we construct some advanced optical qualifications for magnetic quasi Lorentz flux for magnetic quasi- (Formula presented.) particle

Magnetic Flux Density under Single Harmonic Distortion

Materials Science Forum, 2021
In the paper the change of the magnetic flux density under single harmonic distortion is discussed. Presented results show the dependence of the value of the magnetic flux density in the toroidal magnetic core made from the Ni80Fe20 tape of the phase angle of higher harmonic in relation to the main harmonic of distorted magnetizing current.

Magnetic flux density standard for geomagnetometers

Metrologia, 2000
A high-precision standard has been established to create a dc magnetic field in the expanded geomagnetic range 10 µT to 110 µT. Over this range the systematic standard uncertainty of the total magnetic field is (0.003 − 0.03) nT, with a random standard deviation of 0.002 nT, inside a sphere 10 cm in diameter.

Measurement of magnetic flux density vector

2012 6th European Conference on Antennas and Propagation (EUCAP), 2012
This contribution presents a measurement of harmonically changing magnetic flux density in the free space. The components of magnetic flux density vector are measured separately as effective value in the time. The measuring probe and its calibration are described in detail.

Magnetic Hysteresis at Low Flux Densities

Physics, 1935
The 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

Cytogenetic effects of 50 Hz magnetic fields of different magnetic flux densities

Bioelectromagnetics, 2000
Cytogenetic 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 ...

Current and Magnetic Flux Density

2013
We 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.

High torque density magnetically-geared switched flux permanent magnet machines

2015 Tenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2015
Due to the high price of rare-earth magnets, it is pertinent to develop high torque density permanent magnet (PM) machines with reduced magnet volume, which is the main purpose of this paper. This paper proposes novel high torque density magnetically-geared switched flux permanent magnet machines in which the stator is partitioned into two stators but ...

Magnetic flux density measurements in rotating machines

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1955
The Hall effect in a semiconductor is utilized to measure the flux density in the air gap of a rotating machine under transient conditions of starting and loading. This method offers several advantages over the conventional exploring-coil generator. Measurements of the flux density in a synchronous converter were made to demonstrate its applicability.
