Magnet Theory and Selection

No big physics here, but basic facts that should be known when selecting a magnet in a product design

  • attraction force & distance
  • shape: 
  • duration:
  • price
  • resistance:
    • against shock: very brittle
    • against corrosion: good if the outer layer is coated and perfectly intact. Can be very poor if the magnet touches another metal (often the case!) and creates some galvanic corrosion with humidity

Magnet Drawbacks

  • costly if big or if made to order in small volumes
  • not super eco-friendly (rare metals, mix of metals, hard to separate intact when recycling)
  • fragile
  • force decreasing over time (depending on conditions)
  • heavy (metal on the two sides)

Magnet Alternatives

The “specs” of the magnet function to be replaced:

can attach or fix temporary another part, without any additional tool

Note that the “through walls” or “from a close distance” is not an option here, which only the magnet permits.

  • velcro
  • metal clips
  • latches / strap in
