Effect of Tension on Change of Resistance and Thermoelectromotive Force by Transverse Magnetization

Effect on the resistance and thermoelectromotive force of nickel wires, of tension combined with transverse magnetization.—The wires 10 cm long and.14 cm in diameter were stretched while being magnetized transversely with a field of from 1000 to 9000 gauss. The application of tension was found to cause a marked decrease in the change due to the transverse magnetic field, both $\frac{\Delta R}{R}$ and $\frac{\Delta E}{E\Delta t}$ being decreased to half or less by a stress of 20 kg/${\mathrm{mm}}^2$.
