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].
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.
