Thank you both for your response a little clarity here we are producing on a small scale a grown farmed product and then milled in our 3 tests carried out its was noted that there was metal particles in our product minute microscopic particles(probably from machinery0 after looking online at magnetic plate magnets made for food industry I thought we could make one as ones sold for this purpose are super expensive and totally out of our budget thanks again for responses

Good day looking to build a electromagnet that is very powerful and curious as to best power supply(110 or 12 volt) unit will be made from largecopper coil I will source and will have a 24 x 24 inch metal plate on top unit is to attract metal filings from our small milling mill (prototype) that I will attempt to build on our farm with my son unit must be very strong able to pull metal from at least 4 inches away. Any help with materials list greatly apreciated regards steve
