Excerpt from The Magnetization of Cobalt as a Function of the Temperature and the Determination of Its Intrinsic Magnetic Field
In most of the earlier work on cobalt, the object seems to have been to compare its properties with those of iron and nickel. This was probably due in part to.the fact that at that time there was no definite system of units in which to express the results.
Among the earliest investigations is one by E. Becquerel He tested bars of iron, nickel, and cobalt of the same dimensions by observing their periods of oscillation when suspended between the poles of a magnet. He concluded that the magnétisme specirique of cobalt at ordinary temperatures was the same as that of soft iron or nickel. He also states that cobalt loses its magnetic properties at rouge blanc du fer de forge.
