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

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...
