Are the rare earth (?) magnets that control the actuating arm strong

Applied directly, probably certainly if you move them around on the
platters.
Keep the magnets, they're great as very strong fridge magnets. One
holds our 'family cookbook' to the side of the fridge, a collection of
about 25 printed pages...
