Abstract
Electronic devices and accessory devices for electronic devices are described. In some instances, an accessory device includes a keyboard and a cover rotatable with respect to the keyboard. In some instances, an accessory device includes a back panel and a foldable cover rotatable with respect to the back panel. These accessory devices may include several magnetic elements designed to magnetically couple with, and retain, an electronic device without any additional mechanical or other interlocking devices. In this regard, the magnetic elements in the accessory devices provide an external magnetic field sufficiently strong enough to retain the electronic device, and can counter gravitational forces and/or the weight of the electronic device. However, some accessory devices include additional magnetic elements that provide an external magnetic field that repels magnetic elements in the electronic device. Also, the magnetic elements may also be used to hold different sections of the accessory device together.
