Is the effectivity of a magnet only changed by distance or by the intermediate medium (air, wood, tile etc) too?
I want to stick a soap holder to a wall with a magnet hidden behind a tile, but want to know it is going to work beforehand. I dont have a spare tile, but could replicate the distance in MDF)
The attraction force is directly proportional to the magnetic permeability μ of the material in the gap. Fortunately, the values for air, wood, common plastics & concrete are all so close to equal to that of a vacuum that you can disregard them for your purposes.
