Because iron is recognized the major constitute of the Earth's core, and the Bloch-Grüneisen formula holds true in the solid-liquid mixed phase region, the electrical conductivity distribution in the Earth's core was calculated by combining with the temperature structure of the Earth's core with the PREM model. The electrical of conductivities of the Earth's core vary from 4300Ω〓cm〓 to 8400Ω〓cm〓, and increase with the pressures or depth.

既然Bloch-Grüneisen公式被证明在地核的温度、压力条件下及铁的固-液混合相区仍然有效，对于主要成分由ε-铁组成的地核，就允许用Bloch-Grüneisen公式并结合地核的温度结构以及PREM模型计算整个地核（包括液态外地核与固态内地核）的电导率分布。
