A case for an electronic device wherein the electronic device has a receiver coil for wireless charging and the receiver coil is formed in between an inner circle and an outer circle, includes: a hard protective frame constructed to receive the electronic device therein wherein the hard protective frame faces the electronic device; and a metal plate constructed to be received in the recess. The metal plate is constructed to enable magnetic retention or attachment of the case to a support having a magnet. The metal plate has a rounded concave edge, and the metal plate does not overlap with the inner circle. Preferably, the rounded concave edge, the inner circle, and the outer circle are substantially symmetrical with respect to a same line.

Magnetic mount for electronic devices

Devices and products for shielding a mobile electronic device enclosed in a case from an effect of electromagnetic flux generated when a magnetic auxiliary device for the mobile electronic device having a magnet is attached to the case are described. According to one embodiment, the case comprises a protective cover configured to at least partially cover the mobile electronic device and a ferromagnetic plate made of SPCC disposed on the protective cover. In one example embodiment, the at least one ferromagnetic plate is to magnetically couple with the magnet of the magnetic auxiliary device attached to a contact surface of the case, and the at least one ferromagnetic plate is to shield the mobile electronic device from the magnetic flux generated.
