    to attract one another until they were forced apart.

    Foil

  1. The experiment was made to see whether a third piece of platinum foil, P2 would be supported by the attraction of PP'. A very light piece of platinum foil P2 (3/16 inch long by 1/16 inch broad) was supported when the battery was in circuit, and remained supported after the circuit was broken. But if the circuit was incomplete when P2 was presented to PP' no attractive force was manifest.

  2. A piece of copper wire (No.23) about half an inch long was evidently attracted by PP' but was too heavy to be supported.

  3. A piece of platinum foil 3/16 inch square was not supported although evidently attracted. it would remain adherent by its edges for a moment and then fall.
  4. The piece of platinum foil mentioned in Exp.4 was also supported by two copper wires as in Fig 4.
