美 英 na.磁场 网络的磁场 复数:magnetic fields 权威英汉双解 英汉 英英 网络释义 magnetic-field n. 1. 磁场an area around a magnet or magnetic object, where there is a force that will attract some metals towards it 例句
A magnetic field is the region around a magnet or a current-carrying conductor where the effects of the magnetic field can be detected. The field is detected by the mechanical force on iron filings, or on another magnet or on a current-carrying conductor. In some cases the magnetic field ...
1. Understanding Magnetic Field Lines: - Magnetic field lines are visual representations of the magnetic field around a magnet. They indicate the direction and strength of the magnetic field. The lines emerge from the north pole and enter the south pole of a magnet. 2. Analyzing the Density...
