A study of such curves as these reveals the fact that there are three distinct stages in the process of magnetization.
It is attracted by a magnet and may be magnetized, but the magnetization is quickly lost.
Tension produces decrease of magnetization in weak fields, increase in strong fields.
This suggests that the rotation is proportional to the intensity of magnetization, and not to the magnetic force.
The magnetic permeability decreases as the magnetization increases.
In the cyclical reversal of magnetization of iron we have two modes to consider.
He then propounded his brilliant hypothesis that the magnetization of iron was due to molecular electric currents.
The needle, however, being suspended from the arm of a fine balance, its weight is found unaltered by its magnetization.
In a 29% nickel-steel, magnetization increases the constants by a small amount.
Thus there is hysteresis in the relation of magnetization to magnetic force.
