Glass mixed with iron fibres could a magnetic field effect it?

Glass-iron fibres could a magnetic field effect it?

Hi,

didn't know where to post this but basically if we were to have fibres made of a mixture of glass and Iron could an application of a magnetic field be used to apply a strain?

What factors would need to be considered?

Thanks

I suspect the answer is yes.

Do you mean a composite of iron fibres in a glass matrix?

I suppose the factors involved are the same as with any other DFBM composite. Things to think about include fibre length, orientation, wetting, etc.

Do you have a specific application in mind?

Sorry I can't give too much detail, basically a friend of mine posed the question to me (She's a tissue engineer). She basically she plans on growing cells on these glass-iron fibres and wants to determine the effect of stretching the fibres on cell growth.

She didn't give too much detail but she sketched the compound it's basically chains of phosphate bonded to oxygen which is in turn bonded to either Na, Ca-O or Fe-O where the chain is repeated.

I'm just a 3rd year undergrad in physics I don't specialise in materials science.

She plans on conducting the experiment at 37 degrees celcius and one of the concerns was that there would only be a 5% concentration of iron in the fibres. I fugured that may effect the strength of the field required.

EDIT:

I noticed the title of the thread (Itried changing it but it doesn't seem to have), sorry for the confusion, I posted the title but then I found out that the glass and iron is an actual compound making the fibre rather than glass mized with iron fibres.

Ah, I'm not so sure I can help. Perhaps PM one of the regulars in the Materials Engineering section?

There's just not enough information here to make a determination. And even with a complete specification of composition and structure, doing an ab initio determination of the components of the magneto-strain tensor of a new material is a publication worthy calculation.

If the material belongs to class whose magnetostrictive properties have been documented, it may be possible to come up with a fair guess. Alternatively, one might be able to completely discount any noticeably magnetostrictive effects based on the general magnetic ordering in the material. In the absense of that, the best thing to do is the experiment itself.
