Purpose: Training and demonstrations of magnetic phenomena
Ferrofluid is a colloidal solution of ferrite particles with very small sizes (~10 nm) and a surface-active liquid.
Thus, ferrofluid possesses both the characteristics of a homogeneous liquid and the physical properties of a soft magnetic material.
