   3 - resilient magnetic member 4 - non-magnetic member 5 - conducting member 6 - magnetic member 7 - insulating piece. The most common type of reed switch contains a pair of magnetizable, flexible, metal reeds whose end portions are separated by a small gap when the switch is open. The reeds are hermetically sealed within a tubular glass envelope.

   The IBM 305 RAMAC was the first commercial computer that used a moving-head hard disk drive (magnetic disk storage) for secondary storage. [1] The system was publicly announced on September 14, 1956, [2] [3] with test units already installed at the U.S. Navy and at private corporations. [2]

7. Magnetoreception - Wikipedia

   en.wikipedia.org/wiki/Magnetoreception

   When the same mice are allowed access to visual cues, they are able to orient themselves towards home despite the presence of inverted magnetic fields. This indicates that woodmice use magnetic fields to orient themselves when no other cues are available. The magnetic sense of woodmice is likely based on a radical-pair mechanism. [68]
