Consumer electronics
The industry that proved magnets-as-mechanisms at planetary scale — a billion phones now self-align onto chargers with a printed ring of poles.
Consumer electronics is where engineered magnet architecture (if not always CMR’s coding specifically) already ships in the billions. The playbook — self-alignment, gesture release, contained fields next to sensitive silicon — is exactly the coded-magnet behavior list.
MagSafe & Qi2 charging rings shipping
Apple’s MagSafe and the Qi2 standard use a magnet-ring array that self-aligns a phone onto its charger to within about 1.55 mm — alignment-by-field replacing alignment-by-user. The Qi2 standardization pushed the pattern across the whole Android ecosystem.
Breakaway power connectors shipping
The original laptop MagSafe (2006) and Griffin BreakSafe: a cord that releases on a trip-force instead of dragging the laptop off the table. Attach-strong/release-on-motion is the twist-release behavior in its simplest form.
Apple Pencil dock shipping
Magnetic attach + inductive charge on the iPad edge — alignment, retention and field containment in a pencil-sized package.
Lid closures & Hall-effect sleep/wake shipping
Laptop and tablet lids latch magnetically and wake on a Hall sensor — magnets working millimeters from electronics, which is precisely where attenuated-field design earns its keep.
Coded twist-release / attenuated-field phone mounts illustrative
Polymagnet sells twist-release and controlled-field mounting products; specific phone-brand adoption of coded versions is not confirmed. The engineering case — strong hold, gesture release, no compass interference — is straightforward.
Closure “feel” as a brand signature illustrative
The damped, self-seating snap of a well-tuned closure is a designed force curve. Coded detents could make “the click” a specified, ownable product attribute; no brand is confirmed doing this with coded parts.
The takeaway. Electronics already buys what coded magnets sell — alignment, breakaway safety, contained fields. The open question is whether coded parts displace the simpler pole-ring arrays that got there first at commodity prices.
