Abstract
A magnet in a wireless charger and a ferromagnetic target plate in a hearing assistance device are used to create a magnetic retention force to hold the hearing assistance device in place when charging in order to control an amount of interference with a wireless charging occurring between the wireless charger and the hearing assistance device. A housing for the wireless charger has one or more storage areas. The contours of the storage areas each conform to a shape of the hearing assistance device that will be stored in that storage area.
