The Effects of Remote Viewing a Magnetometer

In 1972, Ingo Swan was brought out to Stanford to remote view a magnetometer. According to one version of the story, he was asked to remotely view the magnetometer not necessarily to influence it. And as he remote views it, it starts to behave anomalously and has an effect. That would suggest that more is going on than just precognition if the remote viewing is accompanied by some kind of measurable effect.
