Excessive amounts of electromagnet waves in the environment due to the widespread use of electricity and electrical equipment 由于广泛使用电力和电器设备,在环境中存在过量的电磁波。
Consequently , bec researchers got accustomed to surrounding their vacuum cells with powerful but cumbersome electromagnets 因此, bec的研究人员习惯在真空腔旁,绕上强力却笨重的电磁铁。
When the coil is energized , the electromagnet attracts one end of the armature mechanism , which in turn moves the contacts 当线圈受到激励时,磁铁就会吸引枢轴机构的一端,从而移动触点。
The generator represents magnetron , packaged with constants and electromagnets ( 2 coils magnetic ) in the magnetic - shielded ceramic - metal execution 该磁控管的设计采用电磁石,封装采用金属陶瓷。
If it proves hazardous , engineers may have to cancel out the field within the living quarters using an opposing electromagnet 如果结果显示强磁场有害人体,工程师可能就得利用相反方向的磁场来抵消船舱内的磁场。
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off.
