1. Hall voltage (Hall effect)

V_H	Hall voltage (V)
I	Current across the conductor length (A)
B	Magnetic field (T)
n	Charge carrier density of the carrier electrons (1/m³)
t	Thickness of the conductor (m)
e	atomic unit of charge

2. Hall coefficient

R_H	Hall coefficient (m³/C)
E_y	Induced electric field (N/C)
j_x	Current density of the carrier electrons (A/m²)
B	Magnetic field (T)

R_HE_yj_xB

3. Hall coefficient in semiconductors (for moderate magnetic fields)

4. Hall parameter (due to Hall effect in ionized gases)

β	Hall parameter (dimensionless)
e	atomic unit of charge
B	Magnetic field (T)
m_e	electron mass
v	Collision frequency (1/s)
