Dowling Magnets Iron Filings, Jar (12 ounces) with shaker lid

These filings sprinkled over a clean sheet of paper laid on top of the device whose fields you seek to understand is a very low cost and effective way to make the magnetic circuit visible. Whether the use is professional or instructional these filings are of a size and shape that is very effective of the purpose. Can be re-used indefinitely.

As I was frying up my pork chops, I decided to try this new type of pepper, and oh my God does this stuff taste horrible. Leaves a metallic taste in your mouth for hours after. Crunchy as all get-out. The really strange thing is, we were all on a camping trip when I ate those pork chops, and the next day, everyone's compass kept pointing toward me. Very odd to say the least, and I'm starting to suspect it is the reason I have to avoid being around magnets now as well.Seriously - Great product. Decent price. Works great for making ferro-fluid as the iron filings are very small.

Used these for a demo for our daughters kindergarten class. there was enough in the bottle for us to make 20 small containers with filings in them so all the kids could observe the magnet working through the wall of the plastic. There is nothing cooler than magnets and these were the perfect item and solid quantity to entertain the kids. My wife loved the presentation and wanted to renew our vows afterwords.. all becuase I bought these Dowlings Magnet Iron Filings! Highly recommend.

I would not gift this item...but I’m a teacher and this is perfect for many science experiments we did with magnetism. Fun to mix with sand and then pull out the iron fillings with the magnets through a bottle or clear container.

Did you ever want/need iron filings so badly that you attached the largest diamond bit onto the old speedy driller/polisher tool in your lab/workshop and went to work on an old horseshoe in a vice, collecting the dust and thinking that it would satisfy any semblance of an idea of what iron filings should do in the lab? Well, I didn't either, but that's where I was at when I discovered this product for sale in the form it's packaged in. I've worked with it for a while in my lab and I've not only "passed" it for everything I originally had in mind, but with each test came four or five new ideas and as I've been checking them out, they all worked too. Unfortunately, most of them wouldn't be patentable, nor subject to copyright, but if I trusted you readers on the net not to rip off my ideas and make a half ton of money from them, I'd love to sit here and explain at least half of them to you because they're the kind that make any secret science geek sit up and scream WOW!!! and then the follow-on project is really alot neater still and the scream is more like %!!!!~~&-A... When you order it, get two bottles like I did, so's by the time the first one is all used up, you still have a second one hanging around until your next fresh order comes in.

I am going to resist my urge to provide a sarcastic product review. I will say this is a bottle of iron filings, if that is what you need this is it. Be aware that it is very very fine, (think grains of salt or smaller). If you get this for some purpose other than using with magnets i would recommend you get a strong magnet to assist in cleaning up the inevitable spills. I used this for wiring my finished upper floor from the basement.... yea i know "what does iron have to do with home wiring?"... well i was originally going to place a series of strong magnets on the floor upstairs then see where along the basement ceiling the filings were drawn to and use that as the marker for my drilling points... unfortunately even the neodymium magnets (the 1" cubes) was not enough for this. What did work however was pouring some on the upstairs floor and sliding the magnet along from downstairs with a person upstairs telling me when to stop sliding. Not perfect but it works when you don't have great landmarks to measure from or a very narrow margin for error.

Used for a Science fair project. Worked okay for the experiment.

Product came quickly and as discribed. My kids used them in slime and they were very magnetic. HOWEVER the next day the slime was a rusted blob. Do not use these in anything where they will get wet. Also make sure the kids go outside to wash their hands off after playing with them. My kids washed their hands over the sink full of dishes. The filings left little rust spots on a lot of the dishes.
