这些线圈通常用于选择建立三维图像的切片，但是它们所建立的磁场也能被用来在扫描仪内部的小磁性物体上施加作用。

These coils are normally used to select slices for creating three-dimensional images, but the magnetic fields they create can also be used to exert a force on a small magnetic object inside a scanner.

如果皮肤的自然粘合性移走，磁性也应该起作用——否则就不具有磁性。

With the natural adhesive properties of skin removed, the magnetism either works-or it doesn't.

遮阳天棚将由宽大约为一米的个体飞行物组成，并通过受到磁性发射装置与离子推进的综合作用而被定位。

The shade would consist of individual craft around one metre across, put into position using a combination of magnetic launchers and ion propulsion.

Here this leads to paramagnetism because there is some mutual induction.

这会导致顺磁性,这是因为有相互诱导作用。
