MAGNETIC MATERIAL HAVING SQUARE HYSTERISIS LOOPISAKA AKIRAKUBO TAKASHIMINOWA TOSHIO
Real-time measurement of the magnetic field in an experimental region of space is not always practical or feasible. In most cases, the experimental region is not accessible due to a physical enclosure (e.g., a setup placed in a vacuum chamber), or it could be that placing a magnetic ...
33), the magnetic recording medium (tape or disk) moves relative to an electromagnetic transducer that is essentially a magnetic circuit with a gap. When a current passes through windings about the head, the head is magnetized and a fringe field appears in the gap. In the write process, ...
bar near the top of the figure. Flux lines represent the strength and direction of the magnetic field, where dense lines imply a strong magnetic field. The curved sections attached to the poles are magnetic material (steel or iron), which is used to channelmagnetic fluxin a particular ...
a machine-learned spectral neighbor analysis potential. Since they kept using the Heisenberg functional form, the potential does not consider the change of the magnitudes of magnetic moments due to thermal excitation or the change of local atomic environment. Novikovet al.38developed a moment tensor...
In addition, magnetic materials 11B and 11C for adding a bias magnetic field, which are different in a magnetization level, are attached to the fine wires 1B and 1C respectively so that these wires be different in the magnitude of a magnetic flux inversion field due to an external magnetic...
. Wh corresponds to the conversion loss (loop area) ina static magnetic field, such as that shown in Fig. 3 (a),and becomes the minimum energy necessary to changethe magnetic field direction within the material. That is,materials with a lower coercive force Hc (the thresholdvalue for ...
B and corresponding H loci are plotted and these collected data are analysed by using Mathcad to obtain the core loss curves at different magnitude of magnetic field and frequencies. The findings show that the rotational core loss is increased with frequencies. At 1.8 T under 50 Hz of rotating...
We tested four different field treatments: sole magnetic and electric field exposure, a combination of both and a control without altered field exposure. We show that the 20 kHz square wave electric field was largely homogenous, while the static 0.2 T magnetic field was not. We found that ...
“Methods” section). Similar to that of the Hofstadter model41, the accumulated phase shift of the walker on the lattice is equal to the Aharonov–Bohm phase of a charged particle in a uniform magnetic field, with a magnetic fluxαthreaded through each plaquette. We therefore regardαas the...
