An cylindrical alnico magnet is 1/2 inch diameter and 1 inch long. It is magnetized through its length. I realize that this magnet can be magnitized over and over again. But can the poles be reversed if subjected to a machine that magnetizes and de-magnitezes magnets? Also, where can one purchase such a machine? What are they called? Are there small table-top units availabe for home experiments?
