STEM Box: Ferrofluid (Invented by NASA) (Ages 8 & Up, with Adult Supervision) engineering orientations

STEM Box: Ferrofluid (Invented by NASA) (Ages 8 & Up, with Adult Supervision) engineering orientationsFerrofluid is a liquid (such as water) holding tiny particles of iron compounds that become strongly magnetized in the presence of a magnetic field. You may ask: why don't the tiny particles ever settle out of the liquid to the bottom? The answer is that the particles are submicron size (i. e., nanoscale) so that the surface area of each particle is extremely large in relation to its mass. Because of the small particle size and large surface area, the
