Let's say you have a small SMPS transformer like this one......
Should it show at least some voltage fluctuations at the primary and secondary terminals if you place it in a field of magnetic flux or wave a powerful magnet past it?
I placed this one on top of a powered AC adapter (wall wort) with VOM leads set on AC to the various output pins.
I observed no changes in output voltage.
I then waved a very strong magnet very close to it back and forth and observed no changes in output.
What does this indicate?
