I=j(x)A
evB(z) =eE(y)
E(y)=vB(z)
neAv =j(x)A
E(y) = j(x)B(z)/ne
Constant of proportionality (Hall coefficient) = 1/ne=m³/C = m³/A•s
a metal sample carrying a current along X-axis with density Jx is subjected to a magnetis field Bz(along z-axis). the electric field Ey developed along Y-axis is directly proportional to Jx as well as Bz. the constant of propotionality has SI unit.
1. m²/As
2. m²/A
3.As/m³
4. m³/As
