Emf Detector Circuit. The output signal from the op-amp is an AC voltage at the frequency of the electro-magnetic field. This voltage is additional amplified by the BC109C transistor, prior to being full wave rectified and fed to the meter circuit. The meter is a small dc panel meter with a FSD of 250uA.
Are you a ghost hunter? Then this is the circuit that you've been waiting for! Since it has been observed that appearance of a ghost tends to disturb the EMF, you can now detect any such changes with this little detector.
I need help finding an EMF detector circuit with LED bar graph output. I'm into the ghost hunting world and think it would be great to build my own detector instead of buying a KII meter. I have built other devices for ghost hunting but can't seem to find a circuit on the EMF detector. Thank you for any info or input on this matter.
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.
