Perfect for building electromagnets and science fair projects, it offers easy customization and reliable magnetic performance validated by experimental data. ## Description Use this soft iron rod for a variety of classroom learning demonstrations! Review: Works great for magnetism experiments - Note that these rods are thin. 5mm is about 3/16 of an inch or the thickness of a stack of 5 U.S. pennies. These are easy to cut to length with a hacksaw and work very well for making electromagnets. The relative permeability listed in the description, (86 Β± 3.61) H/m, comes from experimental data by an undergraduate research assistant in physics (a link to the raw data can be found in the comments for this product on the xUmp website) According to the seller's website, these rods are technically AISI 1008 carbon steel made of 99.31-99.7% iron, cold drawn and annealed at 925Β°C. Review: One Star - Don't waist your money not what your looking for ## Features - Great soft Iron rod for use in science fair projects, for building electromagnets, etc. - Measures 20 cm (8 inches) long and 5mm (0.2 inches) diameter - Relative magnetic permeability: 86.00 +/- 3.61 - Contains: Iron, Fe 99.31-99.7 % Manganese, Mn 0.30-0.50 % Carbon, C 0.10 % Sulfur, S 0.050 % Phosphorous, P 0.040 % - Density: 7.872 g/cm3 0.2844 lb/inΒ³ ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008ZV2HB6 | | Customer Reviews | 3.4 3.4 out of 5 stars (24) | | Date First Available | August 20, 2012 | | Is Discontinued By Manufacturer | No | | Manufacturer | American-Scientific | ## Images ![Soft Iron Rod - Image 1](https://m.media-amazon.com/images/I/315iWCAiTeL.jpg) ## Questions & Answers **Q: I want to put this rod in the center of a round wood dowel and have it attach to a neodymium rare earth in a wood tablet. would this work?** A: It is surely magnetic. Depends how strong the magnet is and how thick the wood between the magnet and rod is. **Q: is this solid or hallow?** A: The rod is solid. **Q: Seriously? No dimensions?** A: Yes. I bought these rods "blindly"( with no reference whatsoever); now I know they are: 5.2 mm. (diameter) x 200 mm. (Long) ( too small for the price, isn't it? ) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great for magnetism experiments *by A***D on February 10, 2020* Note that these rods are thin. 5mm is about 3/16 of an inch or the thickness of a stack of 5 U.S. pennies.
