Hi Robert, by measuring moisture content are you referring to the water content
of mined ore? There should be many ways to measure that quickly regardless of
the magnetic qualities. If only a relativistic measurement is needed, maybe try
taking a kilo of material, spread it over a big pan, and heat to 150 degrees
Celsius. Measure how long it takes for the pan to exceed 100 degrees and that
relates to how much water was present. Obviously that's not an accurate
measurement but if you needed something more precise try capturing those vapors
and condensing into liquid water. Or perhaps measure conductivity. Or specific
gravity. Or energy consumed to solidify by freezing. Or absorption of microwave
energy, etc...
