After using the Biot command to compute the field in bus bars (without meshing air)
can I also obtain stress contours and the deformed shape of the bars due to the Lorentz force?

Yes, it is possible to analyze the structural effect of the Lorentz forces using SOLID5 with no air. I have attached an example. It is necessary to use two load steps with BIOT,NEW and NSUB,2 in the 2nd load step. /prep7 et,1,5 !
