Contactless Conductivity Measurement

Introduction

Although it is convenient to measure conductivity using Conductivity Meter, surface preparation and contamination have great effects on the electrical properties of the samples. A contactless technic would be a better way to carry out the conductivity measurement.

To do list

Prepare the samples

Prepare the coils

Build the experimental set up

Measure
