Description
This tube contains many different, loose steel shapes. They are ideal for experimentation with magnetic fields and are a bit larger than the very fine iron filings. With these steel shapes you can also measure magnet strength by counting how many of these shapes are attracted to the magnet. This tube contains many different, loose steel shapes.
