PROGRAMMABLE MAGNET ORIENTATIONS IN A MAGNETIC ARRAY

This disclosure provides methods and apparatus for adjusting magnetic orientations of different sets of magnets in an array. In one aspect, a first set of magnets in the array can be heated. A magnetic field with a first orientation can be applied to the array of the magnets, and adjusting the magnetic orientations of the first set of magnets to the first orientation of the magnetic field. A second set of magnets in the array can be heated and the magnetic field can have a second orientation. The magnetic orientations of the second set of magnets can be adjusted to the second orientation. 本公开提供了用于调节阵列中的不同磁体集合的磁性取向的方法和装置。在个方面，阵列中的第磁体集合可以被加热。具有第取向的磁场可以被施加到磁体的阵列，并且将第磁体集合的磁性取向调节到磁场的第取向。阵列中的第二磁体集合可以被加热并且磁场可以具有第二取向。第二磁体集合的磁性取向可以被调节到第二取向。
