Abstract
A magnetic bail mechanism utilizing opposed, cooperating magnetic means, each having a plurality of magnetic regions which, when in cooperating relationship, contribute torque and provide a tendency for the magnetic means to separate throughout the bail range. The magnetic means interface to provide a maximum separation tendency between the magnetic means at the trip point of the bail and a minimum separation tendency at each of the cast and retrieve positions. The magnetic means provide a torque force urging the bail into the retrieve position when the bail is located between the retrieve position and the trip point and a torque force urging the bail into the cast position when the bail is located between the trip point and the cast position. The magnetic means are prevented from assuming any arrangement whereby facing regions of opposite polarity are substantially axially aligned.
