Hand-Wound Faraday Induction Ring Replica - 28:58 Turns Ratio - Physics Demo

The Materials of History

This is not a mass-produced educational toy, but a meticulously constructed historical tribute using period-correct materials. This replica honors Michael Faraday's 1831 discovery of induction through the use of:

Authentic 1831 Newspaper: The coils are insulated from the core using genuine, original newspaper printed in 1831. This was the exact year Faraday conducted his breakthrough experiments at the Royal Institution.

Antique Iron Core: The toroid is a salvaged piece of agricultural horse tack, providing the necessary high-permeability iron mass for electromagnetic flux, consistent with the "found-object" nature of early 19th-century lab work.

16-Gauge Copper: Hand-wound with heavy, uninsulated copper wire. The primary and secondary coils are separated by the thickness of the 1831 newsprint, just as Faraday used cotton and linen to separate his own windings.

Technical Specifications

Turns Ratio: 28:58 (approximate).

Core Diameter: ~3.4 inches.

Wire Type: 16 AWG solid copper.

Functionality: Fully capable of demonstrating mutual induction when used with a pulsed DC source and a sensitive galvanometer or ballistic pendulum.

Collector’s Note This piece is a bridge between the arts and sciences. The choice of materials—the iron of the field and the printed word of the era—creates a tactile connection to the dawn of the electrical age. It is a striking display piece for any collection of scientific instruments, particularly for those who appreciate the transition from early electrostatics to electromagnetism.

Condition The iron core has a deep, natural patina. The 1831 newsprint shows expected age-related toning but remains structurally sound under the windings. The copper will continue to age and darken beautifully over time.
