Reply to comment by Mr__Teal 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

So, let's make this more clear:

  • a stack of 10 x 1mm thick magnets with a pull strength of 1kg each
  • a stack of 2 x 5mm thick magnets with a pull strength of 5kg each

Would the resulting magnetic force at the end of each stack be the same: 10kg? (give or take a little)

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.
