[HomeBrew] EMF meter?

[Dan K9ZF]

Good morning all,

I have a friend to fashions himself to be an "amateur ghost hunter".  
One of the gadgets they use for this is an EMF meter.  He knows I, being 
a ham,  enjoy building all manor of gadgets, so he asked if I could 
build him one.

I gave it some thought, and figured it should be simple.  We want to 
detect fields, so what I need is a big coil hooked to a volt meter....

So I found a roll of old telephone wire in the junk box.  [probably 
20-24 g, insulated, stranded]  I wrapped about 100 turns on a piece of 
3/4" pvc and hooked it to a DVM.  I then waved it by a florecant shop 
light to test it, and got nothing....

What am I missing?

Thanks,
Dan
