PROGRAMMABLE MAGNET ORIENTATIONS IN A MAGNETIC ARRAY

摘要

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.

1. A method for adjusting magnetic orientations of different sets of magnets in an array, the array including a first set of magnets and a second set of magnets, the method comprising:
heating the first set of magnets in the array; applying a first magnetic field with a first orientation to the array of magnets; adjusting the magnetic orientations of the first set of magnets in the array to correspond with the first orientation of the first magnetic field based on the heating of the first set of magnets and the applied first magnetic field with the first orientation; heating the second set of magnets in the array; applying a second magnetic field with a second orientation to the array of magnets; and adjusting the magnetic orientations of the second set of magnets in the array to correspond with the second orientation of the second magnetic field based on the heating of the second set of magnets in the array and the applied second magnetic field with the second orientation.
