This letter deals with the general concept of magnetostatic modes that are localized around cavities bored in an infinite ferromagnetic medium. The particular case of a circular hole of infinite length inside a material whose magnetization is parallel to the hole axis is studied in some detail. By using an original experimental configuration, it is shown that such a hole supports a very simple fundamental mode which is closely related to the well-known uniform precession of a ferromagnetic rod biased along its axis.
