I am currently looking into using a master magnet to seperate aluminum from food products by AC induction. First, does anyone know if this would be at all possible? I know that recycling companies use Edy machines which sound like the same process of seperating cans from other materials. I am also wondering if this process would be hamrful to use with food because I have only found incidences of this with waste and recycling products. Please let me know what you think.
