摘要：

A hollow cylinder of magnetite at 4 K has been subjected to the simultaneous action of constant axial magnetic field B→ and low-frequency radial electric field E→. The reaction torque, which appears in the magnetite as the electromagnetic angular momentum changes, has been observed for the first time. Preliminary results favor the Livens' reaction-force density -(ε0E→×B→)t and contradict the alternative -(ε0μ0E→×H→)t of Einstein and Laub which was followed by Abraham and is widely accepted by modern authors. © 1979 The American Physical Society.
