Method and an array for magnetizing a magnetizable object
First Claim
1. A method for magnetizing a magnetizable object, comprising:
- applying a first degaussing signal to the magnetizable object to degauss the magnetizable object, the first degaussing signal being an alternating electrical signal having a first frequency and a first amplitude;
applying a magnetizing signal to the degaussed magnetizable object to magnetize the magnetizable object; and
applying a second degaussing signal to the magnetized magnetizable object to partially degauss the magnetized magnetizable object, the second degaussing signal being an alternating electrical signal having a second frequency and a second amplitude.

Abstract
Described is a method and array for magnetizing a magnetizable object. The method includes the steps of (a) applying a first degaussing signal to the magnetizable object to degauss the magnetizable object and the first degaussing signal is an alternating electrical signal having a first frequency and a first amplitude; (b) applying a magnetizing signal to the degaussed magnetizable object to magnetize the magnetizable object; and (c) applying a second degaussing signal to the magnetized magnetizable object to partially degauss the magnetized magnetizable object and the second degaussing signal is an alternating electrical signal having a second frequency and a second amplitude.
