Wireless power transmission device, wireless power reception device, and wireless charging system

A wireless power transmission device comprising:

• a housing having a first side and a second side adjacent to the first side;
• a first coil located within the housing and configured to convert current into a magnetic field that is emitted in a first direction, wherein the first direction is perpendicular to a plane of the first side;
• a first metal member located within the housing and formed to cover at least a portion of the first coil,
• wherein the first metal member is positioned to cause a change in direction of the magnetic field from the first direction to a second direction to provide power to a wireless power receiving device located adjacent to the second side of the wireless power transmission device, and
• wherein the second direction is perpendicular to a plane of the second side.
