Solenoid electromagnetic force

Please login with a confirmed email address before reporting spam

Hi,

I am modeling the electromagnetic force on a square sample area (represents a microscope slide, where magnetic particles will be placed in a gel-like medium for an experiment). I have a solenoid defined and everything is enclosed in a large cylinder of air.

When postprocessing by defining a Force Calculation on a domain, does the "electromagnetic force" global evaluation yielded mean the Lorentz Force (as in the J x B force)? Or is it the integration of the maxwell surface stress tensor?

When I postprocess and plot the Electromagnetic Force, the resultant points "downward" in the -y direction when it seems like it should be pointing in the -z direction instead, towards the solenoid from the perspective of the sample square domain.

I am confused about why this is direction is happening, and about why nothing appears when I attempt to plot the Lorentz Force Contribution.

My model is attached. Thank you for any help.

Tyler
