Homework Statement Consider the Hamiltonian: $$\hat{H}=C*(\vec{B} \cdot \vec{S})$$ where $C$ is a constant and the magnetic field is given by $$\vec{B} = (0,B,0) $$ and the spin is $$\vec{S} = (\hat{S}_{x},\hat{S}_{y},\hat{S}_{z}),$$ with$$\hat{S}_{x}...

Sorry i should have qualified, I know what the symbols represent, and i realize that I_d is given, i also assume I is 0. However what i don't understand is why?

Homework Statement A cylindrical parallel plate capacitor of radius R is discharged by an external current I. The total electric field flux inside the capacitor changes at a rate dΦe/dt = I/ ε0. What is the strength of the resulting magnetic field B(r, I) inside the capacitor at a radial...
