In such cases, it is really useful to simulate the system with a model

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.
