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.

"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.
