This early demonstrational electromagnet was designed for use in 19th or early 20th-century physics laboratories to illustrate the principles of electromagnetism and magnetic field amplification. The apparatus consists of a central coil of tightly wound insulated wire on a turned wooden spool, secured to a robust, tiered circular wooden base. It retains its original solid soft iron core, which freely slides in and out of the central bore. Electrical connections are made via two knurled brass binding posts flanking the central coil. The combination of turned wood, brass hardware, and functional simplicity is characteristic of the period's primary scientific apparatus makers.Condition:
Cosmetics: The turned wooden base and spool retain their original finish, exhibiting standard age-related wear, minor surface scuffs, and natural finish crazing.Hardware: The brass binding posts are structurally intact and display a natural, unpolished patina.Coil: The wire windings remain tight and well-preserved, with no obvious signs of unwinding or significant fraying.Core: The removable soft iron core fits smoothly within the spool and exhibits normal surface oxidation.Functionality: This apparatus has not been electrically tested. It is being offered as a historical scientific artifact for study, restoration, or display.Shipping & Handling:
The instrument will be meticulously packed using quality materials and ample cushioning to ensure safe transit. The shipment will be sent with full transit insurance.
