[QUOTE="jpdemers, post: 1917895, member: 117810"] What determines whether something gets magnetized is its magnetic coercivity ([URL="https://en.wikipedia.org/wiki/Coercivity"]Coercivity - Wikipedia[/URL]). Skipping over the physics and math, it basically means that a magnet too weak to magnetize something doesn't gain the ability to do so if you "just give it enough time." Whether this applies to your particular situation, of course, is anybody's guess. More significant, I think, is that when closed, the flip case magnet is presumably sticking to a metal bar. The magnetic field should be almost entirely constrained to the interior of that bar, with little or no "leakage" beyond it. (You can test this with a paper clip - if a clip sticks to the interior of the closed case, I'd not trust my phone to it.) [/QUOTE]
