In such cases, it is really useful to simulate the system with a model that is entirely without unknown physics and see how the model compares with observation. If it predicts the same phenomena, you can be pretty sure that the outcome was simply outside your expectation. SPICE is a wonderful first-principles tool for a lot of this with wires and magnets.

Indeed.  Seriously excellent advice.

Surprisingly, we've actually had people in the past attempting to find ways to make OU magmos and related gadgets /by using SPICE simulations/, which is kind of unreasonable given that conservation of energy is built into the physics models used by SPICE.

    You may remember the story of the overunity LED,


The OU LED must be /*heated*/ to operate at OU and then it converts some thermal energy to electrical energy. In short, it's no more exotic than a thermocouple, which is doing exactly the same thing.

Both obey the laws of thermodynamics, which is to say you can't just suck power out of it and have it get cold (and then use it as a "cold sink" to make even more energy).

On the other hand, if you're thinking of Stiffler's supposedly OU LEDs about which huge amounts of ink was wasted in this forum a few years back, he was just a scammer. He had a signal generator running, which was capacitively coupled to the circuit providing the power. It was an amusing demonstration of high frequency parasitics, nothing more.
