Why force by electric field is appearing?
I want to ask about the Hall effect. Why is the force by the electric field appearing?
I can understand the appearance of the Lorentz force. However, I do not know for what reason the force due to the ...

How to separate electron and hole mobilities in a intrinsic semiconductor?
I read in textbooks that the electric conductivity of a semiconductor is $\sigma=q(n\mu_n+p\mu_p)$, where $q$ is an electron's charge, $n$ and $p$ are the concentrations of electrons and holes, $\mu_n$...

What's wrong about Maxwell's equations for a Hall probe?
I am using Maxwell's equation to analyse the current and electric field of a Hall Probe. A Hall probe is basically a thin sheet of metal with a current through it. When a uniform magnetic field $\def\...

Switching the position of voltage probes changes the sign of the measured voltage. How can you determine the charge sign in a Hall effect then?
When you measure the voltage in a battery, for example, you place the voltage probes at the battery ends and get, let's say, a reading of 1.5V. If you change the position of the probes in regards to ...
