Neodymium magnet clears metalworking shop

A Russian welder cleans the floor of his metalworking shop with a neodymium magnet. He places his magnet inside a plastic container and then rubbed on the ground. All filings will stick to the container. It remains for him to put the container on top of a box, remove the magnet for all filings fall into the box. This is a rapid technique for the entire chip collecting on the floor. Neodymium enables a very powerful permanent magnet.
