Hi Carol,
I sure wish I was on the big island now.
As a kid, I would take a 110 volt cord with plug and connect a little tin foil in series with a coil of wire to the non plug end. I would stick a magnet in the coil and plug it in the wall. Depending on the phase of the AC current, the poles of the magnetic would get reversed. The tin foil would act as a faster blowing fuse than the house ones.
So the answer is yes. The magnet is still effective with reversed poles.
