If a magnetic field is applied, the BFEC-oil mixture would move in magnetic direction.

在磁场作用下，该混合体向磁场方向运动。

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.

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。

Moreover, turtles responded to the magnetic fields by orienting themselves in a direction that would have led them towards the capture site had they been where each magnetic field naturally occurs.

此外，如果海龟处在磁场自然分布的任何一个地方，他们就会对磁场做出这样的反应，即，引导自己朝向捕食地点。

These use an electric current to heat and ablate a material, producing a charged gas that can then be accelerated in one direction in a magnetic field to push the cubesat in the other direction.

They may cause local changes in the direction of the magnetic field, confusing pigeons that use it to find their way home.

They tend, on balance, to point up, as this means that they are pointing in the same direction as the magnetic field a configuration that is much more stable than the reverse.
