Q1
What is a semiconductor?
A semiconductor has an electrical conductivity value between that of a conductor, such as metallic gold, and an insulator, like glass. Its resistivity reduces as the temperature increases.
Q2
What is the hall effect?
Hall effect is defined as the generation of a voltage difference across an electrical conductor, which is transverse to an electric current and with respect to an exerted magnetic field, it is perpendicular to the current.
Q3
Who discovered the hall effect?
Edwin Hall discovered the hall effect in 1879.
Q4
What is the hall field?
The Hall field is defined as the field developed across the conductor, and the Hall voltage is the corresponding potential difference.
Q5
Give one application of the hall effect.
It determines whether the given material is a semiconductor or insulator.
Q6
Which effect is observed in the charges involved in the electromagnetic fields?
The Hall effect is observed in the charges involved in the electromagnetic fields.
Q7
What is a magnetic field?
A magnetic field is a field that shows the magnetic influence on electric currents, moving charges, and magnetic materials.
Q8
What is a Hall effect sensor?
A Hall effect sensor is a sensor which detects the magnitude and the presence of magnetic fields using the principles of the Hall effect.
Q9
What is a magnetometer?
A magnetometer is a device used to the magnetic field of an object.
Q10
What is the main drawback of Hall effect sensors?
The accuracy of the measured quantities is not considered ideal as there is a chance of interferences by external magnetic fields.
