    Abstract: Examples provide magnets for electronic devices. The magnets can be formed as unitary structures using metal-injection molding. The magnets can be referred to as neodymium magnets. That is, they can be formed of neodymium, iron, and boron. The magnet can comprise a plurality of easy axes, where the plurality of easy axes are not parallel.

    Abstract: An electronic device includes an enclosure and a keyboard positioned within the enclosure. The keyboard includes a substrate and a key mechanism. The key mechanism includes a keycap support mechanism, a keycap supported by the keycap support mechanism and movable relative to the substrate, a ferromagnetic component attached to the keycap support mechanism, and a selectively magnetizable magnet. The selectively magnetizable magnet system may include a magnetizable material and a coil configured to selectively magnetize and demagnetize the magnetizable material. The key mechanism may include a collapsible dome biasing the keycap toward the extended position.

    Abstract: An electronic device can include a first and second portions that are pivotally coupled to each other so that the electronic device can have at least a closed configuration and an open configuration. A magnetic sensor system can be carried by the electronic device to detect the closed configuration so that the electronic device can automatically turn to a mode, such as a sleep mode, when the electronic device is bought to the closed configuration. A magnetic sensor can have a detection axis that targets a horizontal component of a magnetic field. A triggering magnetic element can be laterally offset relative to the magnetic sensor. The magnetic sensor can also be a magneto-resistive sensor. The electronic device can also include a second set of magnetic sensor system to confirm when the electronic device is brought to the closed configuration.

    Abstract: An article having a multiple magnetic polarities and a method for making the article are disclosed. The article can be a monolithic substrate form from a metallic material or materials. The article may include a first magnetic polarity and a second magnetic polarity opposite the first magnetic polarity. Methods for making the article include provide either providing a monolithic substrate having a first magnetic polarity, or applying a first magnetic field to the monolithic substrate to impart a first magnetic polarity. The method may also include raising the temperature of the monolithic substrate in order to reduce the coercivity of the monolithic substrate. The temperature of the monolithic substrate may also be selectively raised to lower the coercivity of the monolithic substrate in associated areas. By lowering the coercivity, the second magnetic polarity may be imparted on the monolithic substrate.
