Abstract: A current transformer core has a ratio of the core outside diameter Da to the core inside diameter Di of <1.5, a saturation magnetostriction ?s of =|4| ppm, a circular hysteresis loop with 0.50=Br/Bs=0.85 and an Hcmax=20 mA/cm. The current transformer core is made of a soft magnetic iron alloy in which at least 50% of the alloy structure is occupied by fine-crystalline particles with an average particle size of 100 nm or less, and the iron-based alloy comprises, in essence, one combination.

Abstract: A magnetic core (1, 1?, 20, 28, 29, 58, 61, 70, 70?, 80, 80?, 90) for a magnetic component has a longitudinal axis parallel to which a magnetic current is to be substantially guided inside the magnetic core. The magnetic core consists of a plurality of magnetic elements (2, 3, 4, 5, 6, 7, 8, 29, 30, 35, 36, 38, 39, 40, 48, 49, 52, 53) shaped like bars or strips arranged parallel to one another, at least one of the magnetic elements (2, 3, 4, 5, 6, 7, 8, 29, 30, 35, 36, 38, 39, 40, 48, 49, 52, 53) is different from the other magnetic elements in one or several of the following characteristics: permeability of material, curvature, length, shape and/or size of surface area, presence, type and location of notches in the magnetic elements.

Abstract: An antenna arrangement for the inductive transmission of energy has magnetic cores made of a composite material with amorphous or nanocrystalline flakes and a moulded plastic material, so that the magnetic properties suitable for effective energy transmission can be adjusted at the same time as high security against fracture and a small overall height are achieved.

Abstract: A highly bendable antenna core (8) which is highly bendable for high-frequency identification systems substantially retains its soft-magnetic properties when bending occurs. The antenna core is produced by using specific amorphous or nanocrystalline alloys having a very low magnetostriction value. The antenna core (8) is embodied in the form of a laminate with/or without insulating layers placed therebetween. An antenna can be provided with one such antenna core.

Abstract: An arrangement has an inductive component with at least one insulating support (1), a magnet core (10, 16), and a winding. The support is provided with several layers (2, 3) of strip conductors which are separated from each other by at least one insulating layer (4). The magnet core is inserted into a cavity (9) of the support, between two layers of strip conductors. Pieces of conductors (5) from both layers are combined especially with through connections to form conductor windings which surround the magnet core.

Abstract: The invention relates to a transductor regulator with a magnetic core which is made up of a nanocrystalline alloy which is almost free of magnetorestriction. The core has as low cyclic magnetization losses as possible and as rectangular a hysterisis cycle as possible. Said alloy has the composition: FeaCobCucM?dSixByM?z, M? representing an element from the group V, Nb, Ta, Ti, Mo, W, Zr, Hf or a combination of these and M? representing an element from the group C, P, Ge, As, Sb, In, O, N or a combination of these and the following conditions applying: a+b+c+d+x+y+z=100%, with a=100%?b?c?d?x?y?z, 0?b?15, 0.5?c?2, 0.1?d?6, 2?x?20, 2?y?18, 0?z?10 and x+y>18. The inventive transductor regulators are particularly advantageously used in motor vehicle voltage supplies, rail power supplies or in aircraft power supplies.

Abstract: A magnetic core has at least two layers (3, 4) of a magnetic material, each layer having a longitudinal axis (L1, L2) and a magnetic preferential orientation (anisotropic direction) (k) at least approximately perpendicular to the longitudinal axis. In order to minimize the coercitive field strength and remanence and to achieve the highest possible quality it is provided that the different layers are oriented, independently of the orientation of the longitudinal axes, in such a way that the angles between the anisotropic directions (k) of directly adjacent layers are as minimal as possible.

The current transformer core is made of a soft magnetic iron alloy in which at least 50% of the alloy structure is occupied by fine-crystalline particles with an average particle size of 100 nm or less, and the iron-based alloy comprises, in essence, one combination.
