How can powder resistivity be measured with 4-point probe?

  1. Dec 21, 2014 #1
    I am studying on Fe powder samples.

    I have used I-V measurement system to get resistivty.

    However, I would like to measure with 4-point probe.

    but I am confused how to prepare the powder sample for 4-point probe.

    could you tell me there is a way?

    How did you measure it with a 2-point probe? You can probably just do it the same way, and use separate wires for the excitation current and voltage measurement paths...
