and this fact has been used by several investigators 1,2,3 to determine the effective permeability of ferromagnetic metals at high frequencies.

Ferrite ceramics and ferromagnetic materials have many unpaired electrons and they align to create a measurable macroscopic field. Attaching an RF ferrite to a cable or looping a cable through a ...

It demonstrated a remarkable combination of properties—ferromagnetism ... and users of the Steady High Magnetic Field ...
