Not so......... Hi Dave, I have attached a Qfield (Ver 3.4, 500 nodes max) screen shot of approx the same sim which shows a force of 29.574 N @ -1.497 deg (to the right). Note the flux distortion of the magnet's field is also to the right. Here in Oz a Newton of force is worth about 100 g of pressure, so if the model had a real depth of say, 10 cm we should expect to see about 290 g of force pushing the magnet into the horizontal centre of the parallel bars according to the Qfield result. Actual duplication of the setup in reality does show a good generation of a centring force on the magnet. Greg
