5. The forces in Fig. 8 are considerably larger than in Fig. 6. This suggests an arrangement in which two short solenoids face one another with a common horizontal axis and with current directions opposed, and the specimen floats between them. This was tried with Al. Stability of the solid was excellent. The melted Al took the shape of a wedge, with the edge down and at right angles to the axis of the solenoids.
