My guess would be that something like that would not have been thought of. Given that the creators of RWBY are from the US, I think it's safe to assume that the cans are made of metal. Beyond that though, what about Pyrrha's weapons themselves? They appear to be made of something like bronze (which would be a strong case for her allusion to Achilles, seeing as how Greek weapons were bronze) which is not a naturally magnetic metal. It's important though to think about the physics of how her Semblance might work, in that aligning the atoms of a metal in the right way causes it to exert a magnetic force. Given that she calls her Semblance "polarity" suggests that this might be true, as she is likely aligning the magnetic poles of the atoms
