### Hall effect source impedance

Background I am an electrical engineer. My friend is a technician in a physics lab and he is using an electromagnetic flow meter (i.e. magmeter) which relies on the Hall effect to measure the flow ...

### About the relationship between Hall coefficient and carrier concentration

I had a question while studying the Hall effect. After going through various intermediate processes, the Hall coefficient can be derived as follows, $R_H=\frac{1}{qn},$ where $q$ is the quantity of ...

### Please explain Hall effect in p type semiconductors without the use of holes [closed]

The movement of holes means the movement of electrons in opposite direction, so in Hall Effect the particles on which force is applied finally must be electrons, so there must be no positive charge ...

### 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 ...

### Why does Equilibrium produce voltage difference in Hall Effect?

This question is bothering me ever since I studied Hall effect. Am I probably missing out a point? To elaborate the question: I understand that Lorentz force and electric force are equal and opposite ...

### How to make sense of the side jump mechanism for anomalous Hall effect?

According to this paper, https://doi.org/10.1103/PhysRevB.2.4559, the electron (wave packet), moving along $x$ axis, undergoes a transverse shift $Δy$ after collision with spin-orbit coupling center. ...

### How can we explain that beryllium has positive charge carriers as a metal (from Feynman Lectures)?

This question naturally arises from reading Feynman Lectures Vol III 14-3 The Hall effect, online available here, where Feynman states the following: The original discovery of the anomalous sign of ...

### How to understand the linear relation between Fermi level $E_F$ and the length $L$ of the slab in Hall effect and spin Hall effect?

I am following this paper to learn the physics of the spin Hall effect. Unlike the conventional Hall effect, the role of the external magnetic field $\vec{B}$ has been replaced by the effective ...

We're doing an experiment to measure the Hall Voltage as functions of current and magnetic field, and we're meant to Compensate the Hall Voltage for $B=0T$. What does this mean, and why do we do it?
