Ferrite-Core AC Hum Precaution

The nonlinear magnetic characteristics of ferrite makes ferrite cores sensitive to hum pickup from stray 50/60 Hz magnetic fields. Ferrite cores should be separated or magnetically-shielded from stray magnetic fields around AC power transformers, motors, solenoids, and other sources of stray alternating magnetic flux. ©2004 Martek International All rights reserved.
