Pieces of reusable zinc-plated iron wire for magnetic field experiments.

• Magnetic properties for suitable for demonstrating magnetic fields
• Fine and easily manipulable texture, but much easier to clean up than iron filings
• Safe and non-toxic material
• 50 g packaged in a reusable storage vial

All of the uses of iron filings for experiments with magnetic fields, with none of the mess! These pieces of reusable zinc-plated iron wire (26 to 27 AWG) 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. Clean up is a snap - no more iron dust permanently clinging to your magnets.
