Electromagnetism and hydraulics

[edimeo25]

hi, I built a crane using hydraulics to move the arm and using an electromagnet at the end of the arm to pick up and move metal objects.... what other applications could use hydraulics and electromagnets?

Mechanical diggers, excavators, dumper trucks, skid steer loaders, backhoe loaders etc all use hydraulic systems with solenoid controlled valves.
