What is meant by Hall Effect?

When a current-carrying wire is put in a perpendicular magnetic field, the voltage can be recognised at a right angle to the current, according to the Hall effect. The hall effect is the method of obtaining a measurable voltage. Edwin Herbert Hall found it in the year 1879.

The Hall effect has the following applications:

  • Proximity detectors are devices that sense the distance between two points.
  • Sensors and probes that use the Hall effect.
  • It's used to calculate phase angles.
  • The influence of the hall The direct current is measured using the Tong test.
  • Magnetic field detection apparatus.

Hall Coefficient Formula

The hall coefficient is a measurement of the Hall effect's strength. It's expressed mathematically as

RH = Vt/(IB)

Voltage, V = RH x I x B/t

Thickness, t = RH x I x B/V

Current, I = Vt/(RH x B)

B = Vt/(RH x I)

  • Where, RH = hall coefficient
  • V = observed voltage difference
  • t = thickness of the conductor
  • I = current running through the conductor
  • B = magnetic field

The charge carriers' type and concentration in the conductor are determined by the Hall coefficient. Its formula is as follows

RH = -1/(nq)

  • Where, n = concentration of the carriers
  • q = charge of a single carrier

FAQs on Hall Coefficient

1. What is meant by the Hall Coefficient?

The product of the magnetic intensity and the longitudinal current density is divided by the quotient of the potential difference per unit width of the metal strip in the Hall effect.

2. What is the Hall Coefficient Formula?

The formula for Hall Coefficient is RH = Vt/(IB)

  • Where,
  • RH = hall coefficient
  • V = observed voltage difference
  • t = thickness of the conductor
  • I = current running through the conductor
  • B = magnetic field


3. Are Hall coefficients always the same?

The Hall voltage is often not a linear function of the applied magnetic field, i.e. the Hall coefficient is not a constant, but rather a function of the applied magnetic field.

4. What is the purpose of the hall coefficient?

The hall coefficient is used to determine the hall effect's strength. The hall effect is the appearance of a voltage differential caused by a magnetic field.

5. Is it possible for the Hall coefficient to be zero?

The electron concentration and carrier mobility affect the Hall coefficient. The conductivity in the insulator is zero if the gap between the conduction band and the variance band is large. When conductivity is zero, mobility is also zero, and hence the Hall coefficient is also zero.
