Magnetic induction was first proposed as a planetary heating mechanism bySonett and Colburn in 1968, in recent years this theory has lost favor as aplausible source of heating in the early solar system. However, new models ofproto-planetary disk evolution suggest that magnetic fields play an importantrole in solar system formation. In particular, the magneto-hydrodynamicbehavior of proto-planetary disks is believed to be responsible for the netoutward flow of angular momentum in the solar system. It is important tore-evaluate the plausibility of magnetic induction based on the intensemagnetic field environments described by the most recent models ofproto-planetary disk evolution.  In order to re-evaluate electromagnetic induction theory the electricalconductivity of meteorites must be determined. To develop a technique capableof making these measurements, a time-varying magnetic field was generated toinductively heat metallic control samples. The thermal response of each sample,which depends on electrical conductivity, was monitored until a thermal steadystate was achieved. The relationship between conductivity and thermal responsecan be exploited to estimate the electrical conductivity of unknown samples.After applying the technique to various metals it was recognized that thismethod is not capable of making precise electrical conductivity measurements.However, this method can constrain the product of the electrical conductivityand the square of the magnetic permeability, or ${\sigma}{{\mu}^2}$, formeteoritic and metallic samples alike. The results also illustrate that alongwith electrical conductivity {\sigma}, the magnetic permeability {\mu} of asubstance has an important effect on induction heating phenomena forparamagnetic ({\mu}/{\mu}0 > 1) and especially ferromagnetic materials({\mu}/{\mu}0 >> 1).
