Abstract

Magnetic elements and attractors may be employed to secure a top case and a bottom case of a housing of a personal computing device. The magnetic elements may include a magnet that produces a magnetic field and a shunt. The shunt may direct the magnetic field through an opening to a pocket in which the magnet is received. Accordingly, flux leakage may be reduced and the bottom case may be secured to the top case. Magnetic elements and attractors may also be employed to secure a lid portion of the portable computing device to the housing thereof. These magnetic elements and attractors may be centered with respect to proximal and distal edges thereof.
