一：magnetic-field是什么意思（中英文）解释的意思

磁场是指由电荷或者电流产生的物理现象，它具有磁性，可以影响周围空间内的物质运动和方向。磁场通常由一个或多个磁极产生，它们可以吸引或排斥其他磁极，并且具有方向性。

A magnetic field is a physical phenomenon generated by electric charges or currents. It possesses magnetism and can influence the movement and direction of materials in its surrounding space. A magnetic field is usually produced by one or more magnetic poles, which can attract or repel other poles and have a specific direction.
