A process for the manufacture of capsules comprising the steps of:

• providing a first population of solid core particles and a second population of fine particles that are smaller than the solid core particles of the first population;
• and
• mixing a liquid with the first population and the second population to thereby form capsules which comprise the solid core, a primary shell of the liquid encapsulating the solid core and a secondary shell of the fine particles encapsulating the primary shell, wherein the primary and secondary shells are generally repulsive to each other.

A process for the manufacture of a magnetic body, the process comprising the step of compacting a mass of capsules to form the magnetic body, each capsule comprising a solid magnetic core, a primary shell of liquid encapsulating the solid core that comprises an anti-oxidant agent therein that inhibits or prevents oxidation of the magnetic core, and a secondary shell of particles encapsulating the primary shell, wherein one of the primary shell or secondary shell is hydrophobic while the other of the respective primary shell or secondary is hydrophilic, and wherein said compacting ruptures said secondary shell to release the liquid of the primary shell.
