Do placebo effects fail when subjects in a blind study are made aware that they have been given placebos? One has to peruse the studies to get specific answers.
Let's remember, though, that copper is non-ferrous, that is, not magnetic! Does it work, even knowing this? I have no clue....

Drug companies carry out double blind studies and often there is a large placebo effect for those who get the placebo. In order for a drug to be approved, it only has to be marginally better than the placebo. For example, let's say 40% of people notice improvement in the control group and 45% find improvement with the active ingredient. That could be considered a success.
