11th - 15th November, 2013

Plan

  • Pick up new components from DMRC

    • Which magnets to use? --> 3mm side cube, 5mm side cube
    • What size of components? --> 50mm radius, 25mm height (earlier 35mm) (done)

    • What gaps between magnet and ferromagnetic material?
      • --> For attraction the gap should ideally be a maximum 2mm. This means that since there is a 0.5mm air gap between the key and the magnet, the wall thickness should ideally be 1mm.
      • --> To ensure there is no attraction between the ferromagnetic material and the magnet (> 3mm side cube) the separation should be at least 15mm
