Magnetization direction is one of the most mis-copied items in a magnet inquiry, because the same word can mean a different arrangement on a different shape. This guide therefore never publishes a direction without naming the shape it belongs to. The six lists below are the complete direction evidence on this site, taken shape by shape from the company's shape pages.

The six per-shape lists
Disc and cylinder: axial, diametrical, axial in segments. Block and plate: through length, through width, through thickness. Ring and tube: axial, diametrical, radial. Arc and segment: diametrical, through thickness, through circumference. Sphere: axial, diametrical. Countersunk: axial, through thickness. No direction is listed for custom shapes as a group, because a custom shape has no standard direction list; a custom inquiry should describe the direction in plain words with a sketch where possible.
Two confusions deserve explicit warning. First, diametrical and radial are not interchangeable: both involve the diameter, but they describe different arrangements, and ring buyers in particular should copy the listed term exactly rather than substituting one for the other. Second, axial in segments is not the same as axial: the segment wording carries a different arrangement for disc and cylinder shapes, and shortening it to axial changes the specification. When a drawing uses a different convention from the listed terms, state the required direction in plain words alongside the listed term so the review can reconcile them.
Direction, temperature and shape together
A direction is confirmed together with a shape and a grade series, not alone. The inquiry should therefore carry all three, plus the operating temperature and the fixing method where they matter. A direction that is assumed rather than confirmed is a common source of a magnet that is dimensionally correct and magnetically wrong for its fixing, and it is worth an extra sentence in the inquiry to prevent it.
