Hall Measurement System

The Hall effect is a phenomena that produce the voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to a applied magnetic field perpendicular to the current. The Hall coefficient is also defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current. The Hall measurement system is designed by our company are most advanced in its specifications and can undertake various tests needed by researchers. The complete system is fully automatic with temperature variation and can go down as low as liquid nitrogen. The system also has option to go beyond room temperature with high temperature options in the same sample holder such as 473K & 773K.

Various tests performed

  • Magneto resistence measurment
  • Current vs Voltage at various magnetic field
  • Hall voltage vs Magnetic field
