Magnetic field inside the ATLAS barrel toroid
I had understood the magnetic field outside a toroid to be zero, but the 'barrel toroid' in the ATLAS detector at CERN I think generates a magnetic field at the centre of the 'barrel' ie. outside of t …

Why (intuitively) do more charge carriers result in a smaller Hall effect?
From the equation for the Hall effect:
$$\Delta V_H= \frac{I B}{n q t}$$
[Where $I$ is the current, $B$ the electric field magnitude, $n$ the density of charge carriers, $q$ the charge per charge carr …
