Ok, so I got a hold of some transformer wire (coated), and decided to make my self a HV transformer.
I took a 7" iron bolt, put 2 large washers at the end to keep the coils in place without spilling over, and i used a power drill to turn the bolt for me while I guided the wire neatly. I used few hundred feet of wire, wrapped without any gaps, made some 30-50 layers onto a bolt. One I reached the top, i continued to wrap the wire down in same direction (always left hand rule). The whole process came out rather nicely.
I measured the inductance (rough estimate, not precise), and it shows about 400 mH (rather low), but ok. DC resistance came out to about 38-40 ohms
Let this be my secondary coil.
I wrapped some regular wire on top of the first coil, about 10 turns, and I connected sig generator to it, 1 Vpp. I connected o'scope to the secondary coil (the one with thousands of turns) and I was expecting voltage to skyrocket when i reach certain frequency....2Vpp max.
What did i do wrong?
Coil is not open, it shows some DC resistance, why is the output voltage so low?
