      Magnets looses his strength at high temperatures.

      Rare earth magnets handle higher temperatures than standard neodym magnets (there are high temperature neodym, but they are more expensive).

      I prefer to use a magnetic foil and a ferro foil. So you have the whole surface as magnetic area.

      I have a similar setup.

            Is there any effect on the silicone heater from the magnetic fields?

              No, but some probes can be affected by the magnets. BLTouch for example. Maybe others?

                  @dallash I'm not too sure really. If it does end up affecting your heightmap you can manually edit the .CSV file to bring the erroneous points in line with the rest.

                  It's possible the newer BLTouch aren't as effected by it?

                  So definitely report back.

                    @dallash There is an option "B1" to stop the bed heater during probing:

                      Railcores probe a mag bed with a BL Touch between the magnets. Do not know if you could do that with the spec of your magnets.
