Summary

Description
English: Magnetization curves of 9 ferromagnetic substances; a plot of the flux density B as a function of magnetizing field H. They all show saturation, the levelling off of B with increasing H that is characteristic of ferromagnetic substances. The graph was traced from a 1917 electronics book, so the accuracy of the data may not be equal to modern measurements.

The substances are:

  1. standard sheet steel, annealed,
  2. silicon sheet steel, annealed, Si 2.5%,
  3. soft steel casting,
  4. tungsten steel,
  5. magnet steel,
  6. cast iron,
  7. nickel, 99%,
  8. cast cobalt,
  9. Magnetite, Fe2O3.
Русский: Кривые намагничивания 9 ферромагнитных веществ: зависимости индукции B от напряжённости поля магнитного поля H. Для всех веществ наблюдается насыщение характерное для ферромагнитных веществ. График взят из книги по электронике 1917 года, поэтому точность данных может не соответствовать современным измерениям.

Вещества:

  1. стандартная листовая сталь, отожженная,
  2. кремниевая листовая сталь, отожженная, Si 2,5%,
  3. мягкая стальная отливка,
  4. вольфрамистая сталь,
  5. магнитная сталь,
  6. чугун,
  7. никель, 99%,
  8. литой кобальт,
  9. магнетит, Fe2O3.
