What is the Effect of Ferrofluid Surfactant on Particle Repulsion?

[wolfspirit]

hi i am a bit confused as to what Steric repulsions are i know that a Ferrofluid surfactant makes Steric repulsions or electrostatic repulsions to counter the van der Waals and magnetic forces to stop stops the particles from collecting or clumping
many thanks for any help
