How to demagnetize a steel shaft

  1. Jul 3, 2006 #1
    How can I demagnetize a steel shaft. Heat is not an option. The shaft is 0.6 inches diameter and 3 feet long.

    Note I have seen several devices for sale that seem extremely expensive. Perhaps, if I know what the actual physical process is, then I can just build a device to demagnetize the steel.

    Also, I have a magnetometer to measure the after affects of the demagnetization process.

    Thanks in advance for any input.
