| 1. | The compass needle if not deflected is no current flows in the wire .
在导线中如果没有电流，指南针就不会偏转。 |
| 2. | A compass needle points ( to the ) north
罗盘的指针永远指向北方 |
| 3. | A compass needle points north
罗盘指针指向北方。 |
| 4. | The massive magnetic field of a powerful mri machine aligns the nuclei of the atoms in the same direction , much as a magnet pulls a compass needle
一台效能强大磁振造影仪的强大磁场能使原子核往同一方向排列成行，就好像磁铁吸引罗盘的指针一样。 |
| 5. | Afterward , compass needles that normally point north would point south , and during the thousands of years of transition , much in the heavens and earth would go askew
后来，通常指向北方的罗盘针指向南方，而在数千年的转换期间，多数在天空而地球会倾斜。 |
| 6. | A compass needle , when placed next to the crystal sphere , will spin counter - clockwise , then commence turning in the opposite direction when moved only inches away
一根指南针,当紧邻水晶球体放置的时候,将会顺时针方向快速旋转,当离开仅几英寸远时开始以相反的方向旋转。 |
| 7. | The good news is that any disappearance of the dipole will be temporary , the halfway point along a southward swing that would leave compass needles pointing toward antarctica rather than the frozen north
值得庆幸的是，磁偶极场的消失是暂时性的，只是一种磁偶极场在做南北方向对调时，在过程中间所发生的现象。 |
| 8. | This effect occurs because the magnetism in the material is generated by innumerable magnetic atoms , like a host of tiny bar magnets , all roughly aligned but randomly fluctuating like compass needles being jiggled about
这是因为材料的磁性是由无数个磁性原子所产生的，就像一群微小的块状磁铁，它们虽大致排齐但仍不规则，就像罗盘的指针一样不停晃动。 |
| 9. | For the next 20 years , the curiosity that was sparked by wanting to know what controlled the compass needle and his persistence to keep pushing for the simple answers led him to connect space and time and find a new state of matter
在随后的20年里，正是由于想知道是什么力量控制了指南针的指向所激发的这份好奇心以及坚持追求简单答案的毅力，引导他将空间与时间联系起来思考问题，由此发现了一种崭新的物质状态。 |
| 10. | Solar wind flows out from the corona the sun s outer atmosphere into interplanetary space at speed of between 300 and 900 km per second . it causes fluctuation to the earth s magnetic field , which we call magnetic storm . such event will cause deflection of compass needles
而太阳风则以每秒300至900千米的速度由日冕太阳外大气层向外抛射，进入行星际空间，对地球磁场造成扰动而产生磁暴，导致指南针指针偏移，严重的话更会导致电力受阻和电话线路中断。 |
