22.1: Magnetic Flux, Induction, and Faraday’s Law

WebSep 12, 2024 · For a loop with N turns, ϵ = − N d Φ m / d t, so the induced emf may be written in terms of the self-inductance as (14.3.5) ϵ = − L d I d t. When using this equation to determine L, it is easiest to ignore the signs of ϵ and d I … WebFeb 3, 2024 · My calculation is. 1 σ ∇ × i = ∇ × E + ∇ × ( v c × H) = − 1 c d H d t + ( H ⋅ ∇) v c − ( v c ⋅ ∇) H = c 4 π σ ∇ × ( ∇ × H) = c 4 π σ ( − ∇ 2 H + ∇ ( ∇ ⋅ H)) = − c 4 π σ ∇ 2 H. … tr was ist das

WebSep 21, 2024 · So taking the curl of Equation 1 gives: (2) ∇ × E ≈ − ∇ × ( v × B) + 1 n e ∇ × ( j × B) + ∇ × ( η j) In the force-free limit, the j × B → 0 and we can use Equation 0b to rewrite the curl of the η j term to give: (3) ∇ × E ≈ − ∇ × ( v × B) + ∇ η × j − η μ o ∇ 2 B Finally we now insert this into Faraday's law (Equation 0a) to get: In magnetohydrodynamics, the induction equation is a partial differential equation that relates the magnetic field and velocity of an electrically conductive fluid such as a plasma. It can be derived from Maxwell's equations and Ohm's law, and plays a major role in plasma physics and astrophysics, especially in dynamo theory.
