ELF Buzz Stick

Product Information

Detects extra low frequency magnetic fields commonly found in our buildings. This simple set up converts the AC magnetic signal directly into a dramatic corresponding sound signal. A 50 Hz powerline field sounds like a 50 Hz hum (a low note on piano keyboard). Harmonics can easily be heard, as well as clicks, static, and hash. LED displays are especially noisy. The strength of the field is proportional to loudness. This device includes a single axis probe on 2 foot cable and audio amplifier with adjustable volume. You can even use an optional earphone/headset for discreet operation. Use it to “sniff out” sources of interference, offending electromagnetic field and check the accuracy of shielding designs. Makes a great educational tool.
Battery: 9V (included).
