Dear Mark, Welcome back. As the model geometry is basically the same the analysis+report takes only 1 hour. In the picture setup.gif you can see the basic setup and magnetic field lines. Generally the force value is lower than in previous configuration. Practically one of the local minima is located very close to the line of interest and the force there is drastically small (17 vs. 94 in previous case). At distance of 30 cm the force/weight ratio is about 7.4.
