Abstract
A method of magnetically separating particles having different magnetic susceptibilities. A magnetic field is established in a colloidal suspension of magnetic particles which distribute to form a magnetic susceptibility gradient. The particles to be separated are introduced into the colloidal suspension. The introduced particles migrate along the magnetic susceptibility gradient to different regions having approximately the same magnetic susceptibilities as the introduced particles.
