Electromagnetic Lifter Diagram - Historical Physics Instrument #93701 (License: Personal Use)

This black-and-white engraved illustration depicts a classic electromagnetic lifter apparatus, featuring two vertically aligned solenoids wound on iron cores, connected by a U-shaped yoke. Current enters through wires at the base (indicated by arrows), magnetizing the cores to attract and suspend a metal ring below. The precise linework and directional indicators reflect late-19th-century scientific illustration standards used in textbooks and lecture demonstrations.

Used in educational contexts-physics classrooms, museum exhibits, or historical science articles-to explain electromagnetism, Faraday’s law, and early electrical engineering devices; targets students, educators, and history-of-science enthusiasts.
