Definition:	specific scaling law of the pinning force density in which the pinning force density $F_{p}$ is given as $F_{p} \propto b^{1 / 2} {(1 - b)}^{2}$ , where $b = {B / B}_{c 2}$ and $B_{c 2} = μ_{0} H_{c2}$ , where $μ_{0}$ is the magnetic constant and $H_{c2}$ is the upper critical field strength Note 1 to entry: This entry was numbered 815-12-27 in IEC 60050-815:2015.
