Claim 0:
1. A case, comprising:
a housing;
a lid coupled to a portion of the housing, the lid configured to rotate around an axis of rotation from a closed configuration in which the lid mates with the housing, through one or more intermediate positions, to an open configuration in which the lid ceases to mate with the housing;
a housing magnet located within the housing, the housing magnet having a first pole and a first magnetic field, the first pole having a first polarity;
a hinge magnet located near the axis of rotation for the lid and having a second pole and a second magnetic field, the second pole having a second polarity, the housing magnet, the hinge magnet, and the axis of rotation for the lid acting as a magnetic hinge, the magnetic hinge configured to enable the closed configuration through a first attraction or repulsion caused by the first and second magnetic fields and the open configuration through a second attraction or repulsion caused by the first and second magnetic fields and passing, through rotation around the axis of rotation, between the closed configuration and the open configuration and through the intermediate positions, the rotation around the axis of rotation through the intermediate positions dynamically transitioning between the first attraction or repulsion and the second attraction or repulsion; and
a magnetic sensor configured to detect a first combined magnetic field when the lid is in the open configuration and a second combined magnetic field when the lid is in the closed configuration.
