Homework Statement
What is J in Ohms law in dynamics?
Homework Equations
Ampères law:
[tex]\nabla \times H = J_f + \partial_t D = J_f + \partial_t ( \epsilon_0 E + P) [/tex]
[tex]\nabla \times H = \nabla \times (\mu_0^{-1} B - M) = \nabla \times (\mu_0^{-1} B) - \nabla \times (M) = \nabla \times (\mu_0^{-1} B) - J_m [/tex]
[tex]\nabla \times (\mu_0^{-1} B) = J_m + J_f + \partial_t ( \epsilon_0 E + P)[/tex]
Ohms law (statics?):
[tex]\sigma E = J[/tex]
Relation between J and p (magnetostatics ?):
[tex]\int_V{ J dV} = \frac{dp}{dt} = \frac{d\int_{V'}{r' \rho{r'} dV'}}{dt} [/tex]
The Attempt at a Solution
Is [itex]J = J_m + J_f + \partial_t (P)[/itex] ?
