Question

Explain how can a magnet attract a piece of iron that is not magnetized?

Answer 1

Some materials, such as the transition elements Fe, Co and Ni, under the influence of an external magnetic field acquire large magnetization, some of which remain as permanent magnetization after removal of the field. This phenomenon is called ferromagnetism, materials with ferromagnetic behavior and is of great importance for various technological applications.
The magnetic behavior of ferromagnetic materials due to the formation of magnetic Weiss areas or areas within them, even without an external magnetic field, in which the individual magnetic dipoles, due to the existence of unpaired electrons in 3d orbitals, interact with each other and are oriented parallel down-stream. This phenomenon is called spontaneous magnetization. In a material that has not been exposed to magnetic field orientation of magnetic moments in magnetic regions is random so that no permanent magnetization appears (Figure 1). The magnetic regions are small areas within the crystalline grains of the material, much smaller than the grains. The boundaries of magnetic regions, corresponding to the grain boundaries, separating neighboring magnetic regions between them and are called walls. The walls of the magnetic regions included a number of people far greater number of people in the grain boundaries and orientation of magnetic moments in these changes gradually from the direction of one of the two neighboring regions to the magnetic orientation of the other

Answer 2

Iron is a Ferromagnetic material ... in ferromagnetic material, there are tiny micro magnets that are called magnetic domains, that are disoriented whose magnetic moment is zero.

When magnetic field is applied, these domains are oriented in the direction of magnetic field and behave as magnetic material

Answer 3

When the influence of a magnetic field in a ferromagnetic material the magnetic regions are beginning to be oriented parallel to it. Initially, the regions where the magnetic moments are parallel to the field expanded at the expense of areas with different orientation. This growth is in areas of displacement of the walls. At first this is done with great difficulty and may require a large increase in magnetic field to induce a small magnetization.

Answer 4

Then, with increasing field strength, growth-oriented areas is easier and hence increases the corresponding slope of the graph and the magnetic susceptibility. When completed the development of the regions, increasing significantly the applied field begins to take place rotation of magnetic regions with different orientation of magnetic moments. This requires significantly more energy than to develop favorably oriented magnetic regions, resulting in the slope of B or M to or reduced. This continues until almost all the regions oriented parallel to the field when the material gets a maximum magnetic induction Bs called magnetic saturation induction

Answer 5

so long story sort
the peace of iron get magnitized due to magnetic fied of magnet and attracts each other

Answer 6

lol thanks for " dumbing it down " for me i was searching everywhere for a basic answer :P

Answer 7

take @experimentX ans
add mine
and i think you are done :)

Answer 8

my short version , no need to say!!! :)

Answer 9

I am not sure about my answer.

Answer 10

i dear to say i am sure enough for both of us :)
but let's wait for a 3rd opinion.....
