The sample was then exposed to a magnetic field applied parallel to the direction of flow of blood via a coil around the edge of the test tube.
然后，将样品放置在通过缠绕在试管边缘的线圈而产生的磁场中，该磁场的方向与血液流动方向相同。

They measured the electrical resistance parallel to the layers and found that it dropped by about 1.5% when they placed it in a magnetic field.
他们测量其平行于层的电阻，发现它放置在一个磁场干扰的地方时下降了约1.5%。

The magnetic field distribution produced by displacement current in charging circular parallel plate condenser is discussed by using the concept of magnetic potential.
