Abstract
A magnetic positioning device is provided that includes a first cup-shape permanent magnet having at least one permanent magnet segment conforming to the first cup-shape, where the first cup-shape permanent magnet has a first polarity, a second cup-shape permanent magnet that includes at least one permanent magnet segment conforming to the second cup-shape, where the second cup-shape permanent magnet segment has a second polarity, where the second cup-shape permanent magnet is disposed concentric to the first cup-shape permanent magnet, where the first polarity is the opposite of the second polarity or the first polarity is the same as the second polarity, where a gap separates the first cup-shape permanent magnet from the second cup-shape permanent magnet, and a connection feature, where the connection feature is disposed on the second cup-shape permanent magnet, where the connection feature is configured to connect a lever arm to the second cup-shape permanent magnet.
