A strong magnet is easy to attach and hard to pull straight off. That is the core problem with magnetic mounts: the force that keeps a phone or cover secure also makes it a struggle to remove.
Twist-to-release pairs solve it with the pattern. When the two faces are aligned, their patterns attract fully. Rotate one part a few degrees and the patterns slide out of correlation, so attraction drops sharply and the part lifts off with little effort. Correlated Magnetics Research's catalog lists twist-release Polymagnet pairs, including a 20 degree version with a detent, an M4 countersink and a 1 inch D-shape, and twist-release pairs sized for mobile devices and small tablets.
CMR has published real uses. A 2016 press release on its site describes the OnYou running armband for iPhone 6 and 6s, where CMR says conventional magnets were either too big or too weak to give both a secure hold and an easy twist-off. CMR's applications page proposes the same action for storm shutters, released by twisting a magnet in each corner.
When designing one in, give the user a clear grip and a rotation stop, and remember the joint resists straight pull far better than torque, by design.
