OG exemplary drawing
 
1. A case for a mobile electronic device having a coil for wireless charging, wherein the coil is disposed in the mobile electronic device and has an inner boundary and an outer boundary, the case comprising:
a protective cover configured to at least partially cover the mobile electronic device; and
at least one ferromagnetic plate disposed on the protective cover,
wherein the at least one ferromagnetic plate is positioned not to block magnetic waves passing through an area formed by the inner boundary of the coil,
wherein the at least one ferromagnetic plate is positioned not to overlap with an orthographic parallel projection of the area formed by the inner boundary of the coil when the mobile electronic device is at least partially covered by the protective cover,
wherein the at least one ferromagnetic plate is to magnetically couple with a magnet of a magnetic auxiliary device attached to a contact surface of the case; and
wherein the at least one ferromagnetic plate is to shield the mobile electronic device from magnetic flux generated when the magnetic auxiliary device is attached to the contact surface of the case.
