Magnetic Instrumentation

What Magnetic Instrumentation does

Magnetic Instrumentation, headquartered in Indianapolis, Indiana, designs and manufactures magnetic measurement and magnetization equipment for permanent magnet producers, motor and loudspeaker manufacturers, and industrial/government research laboratories. The product portfolio spans three core lines: standard capacitive-discharge magnetizers (Models 900, 2000, 3000, 7515A, 8515, 942-B), calibration and demagnetization systems (Models 990A/990C, 5655, 8515-D), and precision measurement equipment including the HG-700 Hysteresigraph, SMT-700 Soft Magnetic Tester, 2130 Fluxmeter, 2100 Gaussmeter/Teslameter, 907A/908A Hand-Held Gaussmeters, Hall Effect probes, Helmholtz coils, the Model 717 Franklin Tester, and the Model 2180 Resistivity Meter. Underlying technology relies on capacitive-discharge magnetization (energy range 100 J to >100 kJ), Hall-effect sensing with EEPROM-based temperature compensation, 16-bit A/D data acquisition, and NIST-traceable calibration through an A2LA-accredited ISO/IEC 17025 laboratory.

The company monetizes through three revenue streams: catalog hardware sales of standard magnetizers, measurement equipment, and probes; professional services including magnetizing, ISO 17025 accredited calibration, NIST-traceable magnetic testing, linear and rotary field mapping, and consulting; and custom engineered magnetic systems plus magnetizing fixtures spanning prototype to high-volume production. Go-to-market is direct enterprise sales with dedicated department contacts for Sales/Calibration Lab, Technical Services, and Magnetic Testing, and no disclosed reseller channel. Customer base is horizontal across permanent magnet manufacturers and users, research laboratories, and manufacturing QA, served globally across roughly 20 countries in North America, Europe, and Asia.

The firm operates KJS Associates (founded 1968 by Dr. Karl J. Strnat) as a wholly-owned subsidiary focused on magnetic materials testing services. With 11-50 employees and over one-third of staff dedicated to engineering — including 17 degree-holding engineers, four with advanced degrees in engineering/magnetics — the business is structured around deep technical expertise rather than scale. The company is privately held, with no disclosed funding, revenue, or external ownership.
