Detailed explanation-1: -Magnetic separation means separating mixtures of two solids with one part which has magnetic properties. It is based on the difference in magnetic and non-magnetic substances. In the mixture of iron and sulphur, iron particles get attracted to the magnet and separates from non-magnetic substances.
Detailed explanation-2: -“Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances.” In this method, the iron nails are attracted by using magnets. Thus, iron nails can be easily separated out from the mixture with the help of a magnet.
Detailed explanation-3: -The mixture of iron filling sand and iodine can be very well separated using magnetic separation because as we know iron is a magnetic material and will be attracted by magnet The mixture of iodine and salt are not attracted by magnet. Common salt, sand and marble can easily be separated by hand making method.
Detailed explanation-4: -Iron filings is a magnetic material while sand is a non magnetic material so they can be easily separated using a magnet.
