随着磁场减弱，太阳黑子的数量会减少到最小值或者说最低点(波谷)，然后太阳的磁场就会反方向运动，开始重新变强。
As the field wanes, the number of sunspots falls to a trough or minimum, at which point the sun's magnetic field reverses direction and starts to regain its strength.
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。
If it proves hazardous, engineers may have to cancel out the field within the living quarters using an opposing electromagnet.
通过求解磁场强度的变化，发现磁场强度最低点随一次地网和二次地网连接点的相反方向漂移的规律。
And then found the law that the lowest magnetic field intensity point location will drift to the opposite direction to primary grounding network and secondary grounding network junction moving.
若线圈有线这么认为电磁场诱导他们转子都是平等的，但相反方向则没有任何阻力的'致线圈，力量相互抵消。
If the coils are wired so that the EMFs induced in them by the rotor are equal but opposite in direction then there is no 'drag' caused by the coils, the forces cancel each other out.
