Problem 3.268

Find the mobility of the conduction electrons in a copper conductor if in Hall effect measurements performed in the magnetic field of induction \(B=100 \mathrm{mT}\) the transverse electric field strength of the given conductor turned out to be \(\eta=3.1 \cdot 10^{3}\) times less than that of the longitudinal electric field.

Reveal Answer
u0=1/ηB=3.2103 m2/(Vs)u_{0}=1 / \eta B=3.2 \cdot 10^{-3} \mathrm{~m}^{2} /(\mathrm{V} \cdot \mathrm{s})
