1 / 6Pages

LABORATORIO ELETTROFISICO AMH-DC-T-S | SOFT MAGNETIC MATERIALS (RINGS) AMH-DC-T-S Permeameter AMH-DC-T-S Permeameter is an automatic DC measuring system to characterize toroid shaped soft magnetic materials. Rings are the best shapes for such magnetic characterization: due to the naturally closed magnetic circuit, the demagnetizing field inside the material is zero. The AMH-DC-T-S meets the International Standards IEC 60404-4, ASTM A341 and ASTM A596. • Remanence Br, coercivity Hc, saturation values Hsat, Bsat, Jsat, cycle area, relative permeability, etc. • Differential permeability • Automatic measurement of complete hysteresis loop, normal magnetization curve and permeability curve • Initial permeability STANDARD CONFIGURATION • Dedicated software Soft2015-P • PC and printer • Connection tool for ring samples • Reference ring for day-to-day control Cabinet containing: • Fluxmeter • 2 DC Power Supplies (including precision current meters)

The sample must be wound with a primary set of NH turns for excitation. A secondary set of NB turns must also be wound around the sample to record the magnetic flux. The H field is determined measuring the current i in the primary winding: H = NH • i /l, where l is the length of the magnetic path (i.e. the averaged ring circumference, when the ring O.D and I.D. are not too different similar). The B field is determined measuring the magnetic flux Φ from the secondary winding: B = Φ/(NB A), where A is the cross section of the specimen toroid. The measuring cycle is fully automatic and is...
