applying magnetic load in Ansys

[Bioengin]

Hi everyone
i want to model the stress behaviour of an artificial organ named CILIA which is made with superparamagnetic materials (i.e Fe3O4) under the effect of harmonic magnetic field.
artificial cilia is a long slender cylinder which has one fixed end and it's other end moves freely in space.
i want to find the stress behavior of cilia under the effect of an identified harmonic magnetic field which has specific amplitude, period and shape. since my analysis is Magneto-structural and 3D, i think the element type which i should use is solid62. i have problems with modeling the magnetic field itself. how should i define a harmonic magnetic field? how should i apply the magnetic load to the cylinder?
I mean because my background is mechanical engineering i have some problems with understanding the electromagnetic degrees of freedom such as AZ,Ay, etc.
I have the required structural and electromagnetic properties(i.e density, Young's modulus, B-H curve and...)
i appreciate your help
thanks

I don't know the answer to your question, but I would suggest you try the Ansys forum:

For cilia lengths that are a fraction of the imposed excitation, that should be easy.

Basically it is a mechanical beam with a distributed load that varies sinusoidally. You can do that. It is all mechanical

The distributed load is proportial to the magnitude of field at a given instant.

you might look under "AFM tapping mode" for inspiration

sounds like fun
