The magnetic field of an alternately charged symmetric 2 N -pole magnet is calculated, using the conformal transformations. The formulae are given for the equipotential line, the line of force, the field strength, the magnetomotive force and the total magnetic flux passing through the surface of...
For a long and thin sample in a parallel field N ≈ 0, while for a short and flat sample in a perpendicular magnetic field the demagnetization correction NM can be enormous. We estimated an effective demagnetization factor N in the studied samples using the measured values of magnetization...
For a given strength of the magnetic field, the spacing between these chains is expected to decrease with increasing confinement (i.e., with decreasing island size) while the overall quality of the patterns is expected to be better in less viscous media (so that the drag forces do not ...
The transformation formula is accurate in theory and suitable for the analysis of magnetic fields with large eccentricity. The rotor eccentricity region in the z-plane is mapped onto a uniform region in the w-plane. The magnetic field solutions are obtained by modulating the magnetic field ...
1. An apparatus for the magnetic treatment of a fluid which produces at least one magnetic field for a period of time, Tc at or above a critical magnetic field strength, Hc, the period Tc and the field strength Hc determined relative to one another and dependant upon the properties of the...
Consider the D82, a grade N42, 1/2" diameter x 1/8" thick disc magnet. The listed Surface Field is 2,952 gauss. You can calculate this number yourself using the formula found in our Surface Fields article. Our Pull Force Calculator does the math for you using the same formula. ...
A modified semi-empirical formula that relates the maximum range of the positron to the strength of different magnetic field strengths is developed via Monte Carlo simulation. The formula is derived as an extension to the existing formula of no magnetic field. COMSOL Multiphysics is used to ...
Under a Creative Commons license open accessAbstract A low-cost and recyclable multifunctional adsorbent for pesticides was successfully prepared based on herb waste (Angelicae Dahuricae Radix slag), nano-zero-valent iron and graphene oxide (AS/NZVI/GO) via facile one-step pyrolysis approach, and ...
A completely new way of using superconducting magnet technology to confine plasma with high energy and extremely high temperatures is proposed. Using the PIC method of microscopic particle simulation, the plasma magnetic nozzle effect and performance of the MPDT under different magnetic-field conditions...
with coercivity of 64 A/m and 230 A/m obtained respectively. The remanence-state magnetization configuration (insets of Fig.2c) for contacted vortex assembly illustrates that interfacial magnetic moment are exchange-coupled and aligned parallelly, which induce an effective anisotropic field and ...
