Magnetodielectric material (often abbreviated as MDM) - a magnetically soft material made as a composite by compressing magnetic particles in a dielectric material, which provides both electrical insulation and mechanical binding properties.

Magnetic properties of the final product depend on the average size of the particles, their shape and packing density. Mechanical properties are dictated mostly by the type and percentage of the binder.2)
Both, magnetic and mechanical properties are critical to production, as well as application of the materials. If used in induction heating they will be exposed to elevated temperatures and must retain ferromagnetic properties under operating conditions.
