I am looking for a Hall-Effect sensor capable of detecting the Earth's magnetic flux. "Electronics" Magazine (Dec 18, 1980) described such a device in a design for building a Hall Compass. Unfortunately, the electronic shops in my area aren't much help in locating unusual items. Can anyone provide me with a address where I can purchase a "F. W. Bell BH-850" flux-concentrating hall-effect sensor?
