one Tesla and higher. It should be born in mind that the average magnetic field of the Earth is 0.00005 Tesla so you don't need to worry about this happening to your television and it's best not to get too close to these experiments with your bank cards.

Now, this phenomenon would be only mildly interesting to beardy scientists wearing sandals if it were not for one very interesting point. These plateaux always appear at the same value of resistance. To a value so exact it makes their toes curl. No matter what temperature or in what type of metal or semi-conductor you measure it in. This means you can take any sample and, without any calibration or checking whatsoever state that plateau number two has a resistance of 12,949 Ohms (to the nearest whole Ohm) and plateau number one has a resistance of 25,938 Ohms. Hence, from this you can then calibrate all those instruments you have had lying about the lab for years, and suddenly all your scientific results become much more accurate, which Physicists like.

Because this was such an astounding discovery Klaus von Klitzing, the very clever man who first observed this effect, won the
