This shows how the standard chassis bends with the magnet in ...........

The C8516 chip shown in the picture blew and had to be repaired due to the extra force required to overcome the magnet. Removing the magnet relieved the pressure and improved the handling characteristics. Fitting a stiffer chassis, if you can get hold of one, is required should you wish to race the card digitally and with a megnet.
