Reply to comment by mustangwallflower in If I have two identical rare earth magnets and put them together, is the power of the combined magnets doubled? What about 3 or 4 magnets (tripled? quadrupled?)? by asdfredditusername

They would basically have the same strength. In reality rare earth magnets have a protective layer on the outside to prevent oxidation so I would expect the stack of thick magnets to be slightly stronger.
