Customer Reviews
Rust freeStephen from Alabama
I'd hunted around a bit for iron rods to make a magnet with my kids and I saw lots of complaints about people shipping high carbon steel or rusty iron. This one came rust free. I haven't tried to test how pure it is, but it did work very well as the core of a magnet.
Product as espectedAurunima from USA, PA, Philadelphia
The item was sturdy and as described. Slightly long shipping time.
Soft Iron RodsC.L. from Clinton, CT
Product was as specified in the description. Although if it's important dia is 5.1mm.
just what I neededJack from Alexandria VA
The rod was excellent in every way. Dimensions were on spec and were uniform along the length. The iron worked perfectly in a coil as a demonstration of solenoid action
Bill L. from USA, Slatington, PA
As advertised! Fast shipping!
Great Purchase!Megan from Wilmington, NC
My son needed these rods for a science fair project. They are great! You may need to cut them to get them into anything smaller than a large Mason jar.
Soft Iron RodKallista Skye from USA, WV, Martinsburg
This item arrived in a timely manner, and was well-packaged. It came with a cute little table of the elements which I foolishly damaged by opening the product with scissors, however.
Not Bad, Good Magnetic Permeability for the PriceAlexander Ogle from U.S.A., OR, McMinnville
This works great for making an electromagnet. I was able to get a field of 10.8 mT at one end of a solenoid running just 367 mA using this as a core. Compare that to the field of 0.12 mT (running 314 mA) I got without the core being present (the solenoid had 255 turns for 22.9cm of length). I called XUMP to see if they knew the relative magnetic permeability for these cores, but they said this listing gave everything they knew, so I ordered 6 of them and decided to measure the relative permeability myself. I measured the relative magnetic permeability to be 86.00 +/- 3.61 You can see my data at the link below, which lists the equipment I used as well. For my purposes, I’ll be needing a relative magnetic permeability of something closer to 1000, but these worked nicely to play around with. https://drive.google.com/file/d/0ByEzSICKIOPkYkJ4SVFJTzg1b1U/view?usp=sharing Questions about the experimental methods can be addressed to aogle@linfield.edu
Good productHilary from Reno, NV
Bought several of these to make strong electromagnets. This is perfect for that. They are about 8" long. It's difficult to find pure iron these days, and this was a good price for my application.
Perfect Raw MaterialKevin Morrow from United States,Kansas,Columbus
Perfect raw iron rod for electromagnetic applications!
