A metal sample carrying a current along x-axis with density Jx
is subjected to a magnetic field Bz (along z-axis). The electric field
Ey (Hall field) developed along y-axis is directly proportional to Jx as
well as Bz. The constant of proportionality (Hall coefficient) has SI
unit
Show answer and solution
Jx = Jx [IMAGE] I = JxA
evdBz = eEy
Ey = vdBz
neAvd = JxA
Ey = [IMAGE] Constant of proportionality = [IMAGE] =
evdBz = eEy
Ey = vdBz
neAvd = JxA
Ey = [IMAGE] Constant of proportionality = [IMAGE] =
