Task id17087
The copper plate has the dimensions shown in Fig. 31.3. With a longitudinal potential difference dfi, current i flows through the conductor. If, without turning off the current, a magnetic field with induction B is created perpendicular to the plate, then a Hall potential difference dfi_h appears between the lower and upper bases. Find the concentration of free electrons in copper and their mobility if l=60 mm, b=20 mm, d= 1.0 mm, dfi==0.51 mV, dfi_H=55 nV, i=10 A, V=0.1 T.
