The report directly from the researchers themselves on the experiments:
Magnometer experiment:
"In another experiment Geller attempted to influence a magnetometer, either directly or by generating a magnetic field. The full-scale sensitivity of the instrument was 0.3 gauss. Throughout the experiment Geller's hand did not come into contact with the instrument. The magnetometer itself was used as a probe to go over his hands and person to make sure that there were no magnetic objects in his hands or on him.
Geller had no apparent difficulty in influencing the magnetometer. He caused fluctuations - almost full-scale in certain cases - whose direction was uncorrelated with the motion of his hands. He was very interested in the experiments we were doing because he had never taken part in laboratory work of this kind before. "
The hidden object can experiment:
"After repetition of this experiment several times, using different objects, Geller was finally able to walk into the room, look at the cans lined up on the table, and just pick up the one that contained the target. "
