New application of the Digital Annealer to maximize flux density
of magnet arrays in energy-harvesting devices
Which Croatian-born electrical engineer had the SI unit of magnetic flux density
named after him?
When developing a superconducting storage device, the following parameters are initial: the energy of the magnetic field of the storage device W, which is necessary for its corresponding application; the properties of a superconducting material--the permissible maximum values of the magnetic flux density
on the winding [B.sub.m] and current density in the conductors [j.sub.m]; the material properties of the mechanical holding system--the permissible values of mechanical stresses [sigma].
HyMag Magnet technology significantly increases the usable magnetic flux density
of a permanent magnet by 10 to 30 percent and produces a less expensive and more environmentally friendly magnet, with 60 to 90 percent lower heavy-rare-earth materials consumption.
Figure 3(a) presents the rotating air-gap flux density
and the resultant torque oscillation due to the standstill rotor and a current of 15.55 A peak/phase at 60 Hz in the stator during IC.
where: B--the magnetic flux density
; [sigma]--conductivity, J--current density; [[micro].sub.0] -permeability of space; M--magnetization vector; v--the velocity of the material.

Because the flux density
is at its highest at the edge of the core, the flux needs to travel through the side wall of the core to complete its path.
"We show that the VLBI/Gaia position jitter correlation with the AGN optical light curve may help to locate the region where a flare has occurred and estimate its distance from the supermassive black hole and the ratio of the flux density
in the flaring region to the total flux density
," they said in (https://academic.oup.com/mnras/article-abstract/471/4/3775/4084982/Observational-consequences-of-optical-band?redirectedFrom=fulltext) the paper.
The PM flux can be controlled independently of the reluctance torque by varying the magnet remanent flux density
and the fraction of the rotor barriers.
where A is the area of each surface in [m.sup.2]; H is their magnetizing field in A/m; the permeability of space [micro.sub.0] = 4[pi] X 1[0.sup.-7], H/m and B is the flux density
in Tesla, at the area of contact between two surfaces.
