EMF detector (HELP ME!)

[Kyma]

Is it possible to build a simple circuit that uses a multimeter to detect the presence of an electro magnetic field?

 

[Styx]

have a search for "hall sensors" and then just strap an OPAMP circuit onto one (plus current source....) then output to DVM.

But in short YES

 

[Kyma]

anybody can find me a schematic for it?

I have Linear Hall Effect Devices and Hall Effect Switches, and there data sheets, Reasonably Priced.
Interested, E-mail me at "chemelec@hotmail.com"
