The precise measurement of electrical resistance is essential in industrial ... of any external magnetic field not only simplifies the experiment, but also gives an advantage when it comes to ...

IN a recent paper, 1 Gerlach and Schneiderhan have described some experiments on the electrical resistance of nickel as a function of the temperature and as a function of a longitudinal external ...

A second experiment can be carried out to investigate experimentally how the resistance of a metallic ... the thickness of the wire decreases. An electric current flows when free electrons move ...
