WA Series Coils

Western Instrument WA Series coils can best be described as Light Duty or Utility Grade MPI Magnetizing Coils. No matter which ID Size, WA-Series Coils have an AC Output of over 4000 Amp Turns on a 115 Volt/60 Hertz Power and over 5000 Amp Turns with 230 Volt/50 Hertz Power. The 4 models of WA-Series Coils are the:

WA-8, AC Coil 8″ ID, 4,250 Amp Turns
WA-10, AC Coil 10″ ID, 4,150 Amp Turns
WA-12, AC Coil 12″ ID, 4,050 Amp Turns
WA-14, AC Coil 14″ ID, 3,875 Amp Turns

As an entry level Mag Coil, WA-Series AC Magnetizing Coils are very economically priced. This economy is a result of our consistency in assembly, and limiting the choices to ID size and activation by a Foot Switch or an intermittent Energize Button. AC Magnetic Particle Inspection Coils are effective for finding surface breaking defects on workpieces with little wear, but where stress results in high load concentrations that in turn can result in component failure. An AC Coil will only affect the surface of a workpiece, and the Eddy Currents that form just below the surface act as a shield to any magnetism in the body of the workpiece. Thus AC Coils only offer a Surface Following Demagnetization field.
