Abstract
This disclosure provides systems, methods, and apparatus, including: a first magnet with a first remanence value and a first coercivity value, the first magnet having a first cross-sectional area substantially normal to a direction of magnetization of the first magnet; and a second magnet positioned in series with the first magnet, the second magnet with a second remanence value and a second coercivity value that is less than the first coercivity value, the second magnet having a second cross-sectional area substantially normal to a direction of magnetization of the second magnet. A ratio of the first cross-sectional area to the second cross-sectional area is equal to or greater than a ratio of the second remanence value to the first remanence value.
