Abstract
A probe for the detection of alternating magnetic fields has a highly permeable probe core (10) and a measuring winding (11) surrounding the probe core, with the measuring winding being put together of several coils (111, 112, 113) which are connected in series. In order to produce a probe which is suitable for the detection of extremely low-frequency alternating magnetic fields from a minimum distance commonly required for the detection of floating bodies that emit such alternating fields, the probe core (10) is put together from flat strips (16) of amorphous or microcrystalline magnetizable material with insulating strips (17) disposed in-between. The coils of the measuring winding (11) are configured as self-supporting coils, preferably as self-bonding wire coils, and surround the probe core (10) with almost no clearance.
