Electromagnetic field detector: (electronic design added 11/06) |
|
Electromagnetic Field Detector #2: This circuit is sensitive to low frequency electromagnetic radiation and will detect for
example hidden wiring or the field that encompasses a transformer. Pickup is by a radial type inductor, used as a probe which responds well to low frequency changing magnetic and electric
fields. Ordinary headphones are used to for detection. The field that surrounds a transformer is heard as a50 or 60Hz buzz. (added 6/06) |
|
Electromagnetic field detector #3: This lovely circuit is a real gem! Easy to assemble and more sensitive than many
commercial devices available. It's based around an LF351 low-noise operational amplifier and a 1mF choke acting as the sensor. Unlike most other simple EMF detectors, this one has a meter
output for accurate reading, but alternatively, you can also roughly estimate the frequency of the field by plugging in headphones. It can detect any field from 50Hz to 100kHz, making it
highly versatile and a worthwhile addition to any hobbyist's workbench. (added 10/05) |
