IEVref: 221-03-40 ID: Language: en Status: Standard Term: magnetic field strength anisotropy factor Synonym1: Synonym2: Synonym3: Symbol: TH Definition: of electrical steel, the ratio of the difference between the peak value of the magnetic field strength ${\stackrel{^}{H}}_{\alpha }$ measured at an angle α to the direction of rolling, and the peak value of the magnetic field strength ${\stackrel{^}{H}}_{0}$ measured along the direction of rolling, to ${\stackrel{^}{H}}_{0}$, at a stated peak value of the magnetic flux density, the ratio being expressed as a percentage: ${T}_{H}=\frac{{\stackrel{^}{H}}_{\alpha }-{\stackrel{^}{H}}_{0}}{{\stackrel{^}{H}}_{0}}×100\text{\hspace{0.17em}}\text{\hspace{0.17em}}%$ NOTE – The measurements of ${\stackrel{^}{H}}_{\alpha }$ and${\stackrel{^}{H}}_{0}$ are to be made under the same conditions.
