[59] evaluated the macroscopic magnetic properties of magnetic composites using the Ollendorff formula, the magnetic circuit method, and the FEM-based homogenization method. The results showed that the contact of magnetic particles in magnetic composites significantly increased the relative permeability. (...
J. Polydoroff refers to the advantages, particularly in the matter of selectivity, which result from tuning radio receiver circuits in such a manner that the ratio of tho inductance to the resistance of the circuit remains constant. These desirable results may be conveniently accomplished by a ...
In the case of composite materials, a simple magnetic circuit model approach including ferrite particle size and volume concentration effects is taken into account.doi:10.1007/s10582-004-0171-7Rastislav DosoudilMarianna U?ákováJozef Sláma
Permeability is the ability to support formation of magnetic fields in a material. Permeability is measured inH/m (henries/m)ornewtons/ampere2(N/A2). The Permeability of Free Space The permeability of free spaceµ0(the permeability constant or the magnetic constant) is ...
which creates a magnetic circuit (electromagnet). The magnetic field also passes across an air gap (center), where fields fringe. Shown is the XY planar cross section of the C magnet, modeled in 2D planar symmetry. Field lines (along constant Az) are in red, and field vectors are also ...
In an industrial environment wherehighvoltages,magneticfields and noise are commonly present, reliability is critical [...] digikey.ca digikey.ca 在工业环境中,通常存在高电压、磁场和噪声,为避免故障停机并确保数据的准确性,可靠性显得尤为重要。
Usually used as magnetic slot and wedge for motor and generator. It can transform magnetic circuit, improve the electromagnetic properties and working efficiency, reduce motor loss and noise, control temperature rising and save more energy. We can machine and futher process...
The primary circuit was fed with a sinusoidal voltage excitation. The primary current was measured by measuring the voltage over the resistor. The magnetic field strength H in the material was calculated from the primary current. The magnetic flux density B in the material was calculated from the...
Soft magnetic materials with stable permeability (μ) produce alternating magnetic flux under magnetic fields driven by current, and serve as the fundamental materials for basic electronic components such as inductor and transformer1. In the newest more-than-Moore integrated circuit packaging technologies...
