A rare find! These pieces of reusable zinc-plated iron wire replace the messy, rust-prone iron powder typically employed in demonstrations of magnetic fields. The short pieces of wire align themselves linearly to provide an excellent representation of magnetic lines of force. Use them to your advantage in any demonstration requiring clear, curvilinear force lines.
