"Contactless Dynamo" / Wind generator showing weird multimeter readings? Answered
I am trying to replicate this, more or less, It's a setup using hard drive magnets and the coil from a relay to generate electricity. My problem is that every configuration I have tried gives me weird negative and positive numbers(around -20 to 20, constantly changing while the magnets are spinning), and only in the hundredths of volts setting(on the multimeter, the volt, and thousands of a volt settings show nothing). I have tried using: hdd magnets and round magnets (8 of them in a N-S-N configuration); a relay coil, a small transformer coil, and winding my own coils 3 times. The hand-wound coils have approx. 159 turns, 200 turn, and 250 turns, all with thin very thin enamel-coated wire, as it's my understanding that thinner wire will output more voltage. No matter what configuration, I get the same erratic readings. What am I doing incorrectly?
