A Mathieu‐type pendulum magnetic balance is described that employs the Faraday principle for measuring the specific magnetization of ferromagnetic materials. The balance can be operated automatically, or deflections may be read optically. The sensitivity of the balance can be varied twenty‐fold by changing the weight distribution, and the calibration remains constant for years. Specific magnetizations are obtained with a precision of ±0.3%. Field strengths up to 10 000 oe can be held constant within ±0.3% for several hours. Specimens can be heated to 800°C or cooled to −180°C, and the temperature can be held constant to ±1.0°C for isothermal measurements. Automatic heating of the specimen at constant rate is provided.
