I am designing a 16-foot magnetic assembly that will be mounted on a trailer to collect steel wire and scraps off the ground. The long-range (10-inches) field strength is important due to many pieces being partially buried and having uneven ground. The basic idea involves a Halbach array of neodymium magnets enclosed in an aluminum housing. If I want to extend the field even farther would adding a steel bar to the strong side of the array increase the strength of the field farther out or would it cancel the advantages of the Halbach Array?
The additional steel would be mounted in the center of the array similar to the example here: Link
