Im trying to craft a homemade transformer. I dont need any specific voltage/ current, Im just experimenting.
The problem im having, is that I just cant get my secondary coil to register any voltage at all.
Ive used both ferrite beads, and cylinders, and also steel rod as the core.
Im wrapping around the core a 36SWG copper enamled magnet wire.
No matter how many turns I do (primary or secondary), when I 'pulse' 9V through the primary, no voltage appears on the secondary!
If I repeat the same experiment with a proper salvaged transformer, the multimeter reads a brief voltage, as you would expect.
Does any one have any ideas where im going wrong?
Many thanks
