Hydraulic Magnet
From RitchieWiki
A hydraulic magnet is an electromagnetic tool used in demolition or in scrap yard operations for separating and picking up steel and other ferrous metals from other debris. It is then transferred to a metal shredder or other scrap processing machine. The hydraulic hammer, mounted on a crane, excavator, or similar type carrier machine, is powered by a generator that creates the electricity needed to produce magnetic fields.
