Abstract
A tablet information handling system selectively couples to a charging stand and charging dock with opposing sets of spaced magnets to have magnetic attraction hold a wireless charging receiver aligned with a wireless charger. Magnetic attraction is greatest when the tablet information handling system couples in a landscape or portrait orientation and is reduced for removal of the tablet information handling system by rotating to an offset orientation so that magnets align with opposing spaces, resulting in a reduced magnetic attraction. A sensor disposed in a space detects the offset rotation by detecting the increased magnetic flux of the magnet aligning with the space so that a user interface can provide an end user with an indication that the tablet information handling system is positioned for separation from the charging stand or charging dock.
