In current through a conductor joule heat generated by the electric furnace for the heat source.

以电流通过导体所产生的焦耳热为热源的电炉。

Electromagnetic induction: when a conductor of a closed electric circuit move cutting the magnetic induction lines, the conductor produces current.

电磁感应现象：闭合电路的一部分导体在磁场里做切隔磁感线运动时，导体中就产生电流的现象。

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。

Current conductor Lockhart says one of the most exciting - and well-attended - events of every Boston Pops season comes on the evening of July Fourth.

Don Melrose, also at Sydney, points out that the gas in the middle of the galaxy might already be so strongly ionised, and thus such a good electrical conductor, that current would leak away rather than build up into a concentration like the Snake.

ECONOMIST: Here be serpents

The system consists of sensors fitted on cables throughout the network, both overhead and underground, measuring current and conductor temperature.
