Part 2/8:
The graphite from industrial or hobby stores often exhibits uneven surfaces, inconsistent thicknesses, and rough edges, as seen in some of his earlier samples. In contrast, Adam's pieces are beautifully cleaved and precisely cut, with smooth, consistent edges and even thicknesses, making them more suitable for experiments and demonstrations. Paul highly recommends sourcing pyrolytic graphite from this trusted supplier, noting his reasonable prices and careful cleaving techniques.
Experimenting with Different Shapes and Sizes
Paul proceeds to experiment with various pyrolytic graphite pieces, starting with larger wafers and moving to smaller ones. He demonstrates how these pieces interact with a set of powerful neodymium magnets, highlighting several key observations:
