The Electromagnets of The Junkyard

This giant electromagnet is used to pick up heavy metal in junkyards! There is a wide range of electromagnet sizes and strengths used for this task. The need to pick up massive metal objects causes these magnets to be quite strong at times. Thus, these junkyard magnets typically have a considerable magnetic field strength of 1 T. The power output in junkyard magnets range from 1 to 30 KW in lifting 100 to 100,000 pounds of metal. (See CANMAG 230V DC Series Magnet Brochure) These powerful electromagnets can even be used to lift stuff beyond the junkyard, such as in construction sites and metal scrapyards, of course.
Junkyard electromagnets are a rather simple version and application of electromagnets. The electric current applied through the magnet produces a magnetic field which attracts other magnetic objects. Yes, these electromagnets are limited to lifting only magnetic metals such as iron, nickel, and cobalt. But these metals are used in piping across the world as well as in everyday metal objects. Thus, these electromagnets prove to be useful in lifting much of the metal we throw away or recycle. Clearly, these giant electromagnets are versatile and useful in lifting heavy, magnetic metals.
