Abstract
The apparatus is used to make a magnet with a plurality of magnetic pole pairs. One or more pole pairs is formed by the apparatus as an initial step. Thereafter, additional pole pairs are formed by moving the apparatus with respect to the body to be magnetized or moving the body to be magnetized with respect to the apparatus. The apparatus is constructed so that previously magnetized portions of the magnetizable body are not demagnetized or significantly altered by the magnetization of adjacent parts of the magnetizable body.
