About KJS Associates, Inc.

Since its founding in 1968 by Dr. Karl J. Strnat, KJS Associates, Inc. (KJSA) has specialized in all aspects of magnetic materials testing. The two major areas of activity are magnetic measurement services and the design, construction, and sale of high-quality magnetic test instrumentation and fixtures. The company also offers training and seminars on magnetic topics which can be presented at the customer's facility or at KJS Associates, Inc.

MAGNETIC TESTING SERVICES: KJSA characterizes the magnetic properties of permanent magnets and magnetically soft materials on a confidential basis for industrial and government clients. As an independent test laboratory, KJSA can provide accurate B vs. H and (B-H) vs. H magnetization curves, measured on any type of permanent magnet material over a temperature range of -150șC to +350șC using computer-automated equipment. Testing is certified traceable to NBS (now NIST) standards. A large range of sample geometries can be accommodated and KJSA has in-house cutting and grinding equipment for sample preparation, when required. Additional capabilities include measurement of reversible and irreversible losses of flux, magnetic aging of test samples at various temperatures, and determining temperature coefficients of flux and coercivity. KJSA can test magnetically soft materials for maximum permeability, saturation magnetization, loop shape, and coercive field under DC conditions, as well as AC permeability, B vs. H and core loss testing from 10Hz to 50kHz.

MAGNETIC TEST SYSTEMS: KJSA is a manufacturer of magnetic hysteresigraphs, search coil fixtures, magnetic calibration standards, coercimeters, electromagnets, magnetizing coils and custom magnetic testing equipment. An area in which KJSA has particularly distinguished itself is in developing commercial methods and fixtures for measuring accurate magnetic hysteresis loops of permanent magnets in the closed magnetic circuit at temperatures between -100șC and +300șC. Equipment ranging from an individual coil set or calibration standard to a complete turnkey, computer-automated test station can be provided. Most fixtures can also be made compatible with other brands of hysteresigraphs and permeameters.
