ferromagnetic's Usage Examples:

Negative magnetic hysteresis Ferromagnetic materials posses the property of magnetic hysteresis.

ferromagnetic phases of the manganites can be used as a source of highly spin polarized electrons, e.g. for spin electronics and quantum computing.

ferromagnetic metal into a semiconductor, the resistivity mismatch problem has to be overcome.

ferromagnetic layers introduce the spin assymetry needed to make use of the electron's spin.

Demagnetizing Force.-It has already been mentioned that when a ferromagnetic body is placed in a magnetic field, the resultant magnetic force H, at a point within the body, is compounded of the force H o, due to the external field, and of another force, Hi, arising from the induced magnetization of the body.

When induction or magnetic flux takes place in a ferromagnetic metal, the metal becomes magnetized, but the magnetization at any point is proportional not to B, but to B - H.

The fact being established that magnetism is essentially a molecular phenomenon, the next step is to inquire what is the constitution of a magnetic molecule, and why it is that some molecules are ferromagnetic, others paramagnetic, and others again diamagnetic. The best known of the explanations that have been proposed depend upon the magnetic action of an electric current.

It is found that when a piece of ferromagnetic metal, such as, iron, is subjected to a magnetic field of changing intensity, the changes which take place in the induced magnetization of the iron exhibit a tendency to lag behind those which occur in the intensity of the field - a phenomenon to which J.

ferromagnetic objects can pose a serious safety problem.

If the wire consists of a ferromagnetic metal, it will become " circularly magnetized by the field, the lines of magnetization being, like the lines of force, concentric circles.
