two equal and opposite poles + m^ at r. The six poles now in the field can be takenin three pairs so as to constitute three doubletsof strengths m^.

The matter occupying any element of volume dxdydz at this point willbe a magnetic particle of which the moment is I dxdydz and the axis is indirection I, m, n.
