Loosely stated, this says that an electrical current in one conductor will induce a current in a second, wholly separate, conductor that shares the same magnetic field.
简单说来，就是通入电流的导体能使相离的另一导体感应产生电流，并形成同一磁场。
The second voltage creates an electrical field, which is preferably located in the vicinity of the ion cloud.
第二电压产生电场，该电场优选位于离子云的邻近处。
