Ferrocell, an awesome magnetic field viewer, magnetic field perception is undoubtedly better than any other system. It's easy to make, but be careful, ferrofluid dirt terribly so take precautions to not ruin what's around. You need: 2 glass sheets or transparent acrylic material Ferrofluid https://sumag.net/ferrofluid-xmg01 Mineral oil to dilute the ferrofluid A led strip to highlight the rotation of the ferrocell magnetic particles Magnets of all shapes and sizes, all you see in the video come from https://www.supermagnete.com Do you need more info about ferrocell? download this interesting work "Controlling light diffraction using magnetic nanostructures" https://briefs.techconnect.org/wp-content/volumes/TCB2019/pdf/116.pdf LIKE & SUBSCRIBE HERE: http://bit.ly/Sub2MagneticGames WATCH MY TOP VIDEOS HERE: http://bit.ly/MagneticGamesTopPlaylist On my channel you will find all the ways to have fun with magnets divided into 3 main categories: Classical magnetic experiments such as magnetic levitation, homopolar motors, small magnetic weapons, Gauss cannons, gears, magnetic field viewers and much more.
