Beschreibung
Zusammenfassung:	FIELD: magnetic measurements, specifically, measurement of coercive force of tested sections of articles in case of nondestructive magnetic inspection. SUBSTANCE: coercimeter incorporates solid yoke into which cylindrical hole magnetic units mounted for autonomous rotation are installed. Units are formed by permanent magnets in the form of plates made of highly coercive material and inserts produced from low-coercitivity steel in the form of segment cylinders bordering on them. Handles to ensure autonomous rotation of magnetic units on steel inserts are fixed on opposite sides of yoke. Yoke carrying scale of reading of angles of turn of magnets is positioned on inspected article. Converter of magnetic flux is located in lower part of yoke, or it can be mounted between yoke and article. Magnetic units can be replaced when necessary. EFFECT: high measurement precision, low mass and reduced energy consumption. 4 cl, 2 dwg
