Magnetic susceptibilities of coals.
Magnetic susceptibilities are reported for seven American coals of different rank. The susceptibilities were measured in magnetic fields parallel and perpendicular to the bedding planes. The coals have diamagnetic susceptibilities approximating -0.5 x 10(-6) centimeter-gram-second unit. Only anthracite shows significant magnetic anisotropy.
