For example, one of the experiments we do is measure the magnetic field of current coil, and after we do the experiment, we all have a passive visualization that shows the same experimental set-up, except we add to that.

比如，我们做的一个实验就是,测量电线圈的磁场，在我们做完实验之后，我们都感受到了一个直观化的过程,它展现了同样的实验过程，只是那是我们加的。

By holding a magnetic coil over somebody's skull, a researcher can affect the activity of the piece of cortex beneath, while causing no pain to the subject.

ECONOMIST: The ethics of brain science

One new technique being used by some neuroeconomists is transcranial magnetic stimulation, in which a coil held next to the head issues a low-level magnetic pulse that temporarily disrupts activity in a certain part of the brain, to see if that changes the subject's preferences for example, for a particular food and how much he is willing to pay for it.

Instead, the coil is pulled through the external magnetic field, which induces a voltage across it.
