Angular time delay

The angular time delay of the longitudinal magnetic flux in the steel wires behind the magnetizing force varies with the particular sample of steel. Unless reference can be made to measurements on the steel wire to be used, some average value must should be assumed. No appreciable error is involved if, for wires of diameters from 4 mm to 6 mm and tensile breaking strengths around 400 N/mm$^2$, a value of $π/4$ (45°) is assumed.
