Summary

[edit]
Description
English: Surgical electromagnet made by Westinghouse Co. in a medical clinic in an East Pittsburgh, Pennsylvania, USA steel mill in 1915, used for removing metal foreign bodies embedded in the eye or other parts of the body. Its operation is demonstrated. The pointed pole piece of the electromagnet is brought near the eye, the power is turned on, and it pulls the body out of the eye. This is less invasive than using tweezers. The magnet comes with several replaceable pole pieces for different purposes. It runs on 70 to 120 V and consumes 4000 watts. The rehostat on the side is for adjusting it to different supply voltages.
