Low frequency electromagnetic noise
Low frequency electromagnetic noise
(OP)
Do you know of simple ways to measure low frequency electromagnetic noise in environment? I encountered this problem when designing some basic bioelectric transducers. I understand that sensitivity to such noises can be minimised when using differential amplifiers and 50/60Hz filters but sometimes it is usefull to compare different places by amount of such noise or locate devices that generate most of unwanted interference. Any ideas?

Possibly www.fwbell.com, or [one-man operation no web site, AFAIK] produces a simple multimeter accessory:
