All my appliances, range hood and much of the BBQ are stainless and I have a custom-cut stainless panel as a backsplash behind the range. The only non-magnet-attracting items are the Bosch range and the backsplash.

Dishwasher and fridge are Fisher Paykel with mild-medium magnetic attraction and the range hood is Zephyr with stronger attraction. The tables and door on the Napoleon BBQ are very much attracted to magnets.
