Definition: | of electrical steel, the ratio of the difference between the peak value of the magnetic field strength ˆHα measured at an angle α to the direction of rolling, and the peak value of the magnetic field strength ˆH0 measured along the direction of rolling, to ˆH0, at a stated peak value of the magnetic flux density, the ratio being expressed as a percentage:
TH=ˆHα−ˆH0ˆH0×100 %
NOTE – The measurements of ˆHα andˆH0 are to be made under the same conditions.
