Negative Inductance and measure of Magnetic force.

I'm setting up to power the 1.81 Henry inductor with a "Sinusoidal Audio Spectrum" generator and blue tooth amplifier. The coil electrodes connect to the two wires from the earphone adaptor. 1 to 20,154 Hertz.

Here's an excellent free online tone generator:

I fried my $1200 Mac laptop feeding audio into the powerful two disc neo 1.81 Henry electromagnet at too close a distance. I don't feel too bright right now.

The 1.81 Henry coil needs a 7 Pico farad capacitor to resonate at a sine wave audio frequency of around 500 Hertz. The idea is to reinforce the LC resonance with the audio input and oscillate the magnet field to generate power out. I need to recover my hardware before I can try this.

Sorry to hear about the computer.
If it's any consolation, I don't know any experimenter that hasn't accidentally blown some equipment up in the process.  My first few years learning about these systems probably generated more smoke than power.


Good work with your experiments.  I have a few of the same electromagnets but have not had nearly the amount of success.

@Reiuki,

The screen blacked out. I'm shopping for an external VGI display adapter. Describe to me what you're up to, maybe I can help out. Do you have a spring pressure SPDT switch like the one I showed earlier in this thread?
