Ferrofluids! One of the clichéd science tropes of teaching... But that doesn't make it any less interesting! Join Jonathan as we dive into the world of magnetic rocket fuel, nano particles and future applications of magnetite in a colloidal solution.
00:00 Into to What is ferrofluid?
00:28 What is a Colloidal liquid/ colloid fluid.
03:15 The history of Ferrofluids.
Ferrofluid is a unique material that acts like a magnetic solid and like a liquid. Ferrofluid is made of tiny, nanometer‐sized particles of coated magnetite suspended in liquid. When there’s no magnet around, ferrofluid acts like a liquid. The magnetite particles move freely in the fluid. But when there’s a magnet nearby, the particles are temporarily magnetized. They form structures within the fluid, causing the ferrofluid to act more like a solid. When the magnet is removed, the particles are demagnetized and ferrofluid acts like a liquid again.
