Lifting magnets aren’t your average refrigerator magnets. Some are the size of queen beds. Lifting magnets are used in industrial settings. Magnets are often seen at scrap yards where they are used to move scrap steel and cars. Lifting magnets are also used in steel mills to safely and efficiently move newly made steel. Magnets are also found at shipping yards and ports to easily move shipments from one vehicle to another.
If you see a lifting magnet, they are very powerful. You should never walk or stand below a lifted magnet.
Fun fact: Steel begins to lose its magnetic properties at roughly 1000 to 1200 degrees F. Steel becomes completely non-magnetic at 1325 degrees F.
