How do MagSafe magnet arrays work? N52 vs. cheap magnets
Not all magnet rings are equal. We compare n52 neodymium magsafe magnet specs with cheap rubber magnets.

Many cheap cases claim MagSafe support, but their magnets are weak. This is because they use cheap rubber-iron composite magnets instead of a premium n52 neodymium magsafe magnet array.
N52 Neodymium is the highest grade of rare-earth magnets available. They provide massive magnetic pull force in an ultra-thin profile.
At The iPhone Project, we embed 36 individual N52 magnets inside a copper alignment frame. This keeps your phone securely locked to car mounts, desk stands, and wallets even over major road bumps.
