You won't be able to make a true ferrofluid (that is, a silky smooth, low viscosity, inky black fluid), but you can indeed make a more 'chunky' magnetic fluid. You'll need strong magnets. **Q: Would this be a good choice for making ferrofluid?** A: In short, no! I was mislead by the first answer to this question and bought a bag to play with. The problem is particle size; ferrofluids require particles under about 10 nanometers and these are (claimed to be) 1 micron (1000 nanometers) in size. Far too large for ferrofluids, but I think I'll find something interesting to do with the stuff. **Q: If made into putty or ink, is there a way to get this stuff to attract 'itself'? Ex: Spread the magnetized ink on 2 sheets of paper.** A: It seems to just lay there and do nothing on it's own. I made the putty (be sure to ware gloves when making it - it is OK to handle later) You have to have a really strong magnet to attract it - - it is a fun science lab for kids but the Fe3O4 is not magnetic it is attracted by a magnet. It can be really messy ! **Q: Is this suitable for making cosmetics? Cosmetic grade , if you will?** A: Yes. I actually saw a video where the woman had used for cosmetics. She did much research and found that it was suitable and safe for cosmetic purposes. ## Frequently Bought Together - Black Iron Oxide - Fe3O4 - Synthetic - 1 Pound - MIKEDE Strong Rare Earth Neodymium Magnets, Heavy Duty Bar Magnets with Double-Sided Adhesive, Powerful Pull Force, Perfect for Fridge, Garage, Kitchen, Science, Craft, Office, DIY 60x10x3mm 6pack - DIYMAG 1" Cube Neodymium Magnets, One Inch Cube Rare Earth Magnet - Grade N52, Pack of 2 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/3686340-black-iron-oxide-fe3o4-synthetic-1-pound](https://www.desertcart.in/products/3686340-black-iron-oxide-fe3o4-synthetic-1-pound) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-22*
