Skin Depth & Proximity Effect
δ = √(2/(ωμσ)), current crowding in round conductors, proximity effect, and estimated AC resistance vs frequency.
Debye Shielding in a Plasma
Test charge in an electron plasma: Yukawa potential φ ∝ e^{-r/λ_D}/r, λ_D = √(ε₀k_BT/n_e e²), 2D map and λ_D vs T, n.
Langmuir Plasma Oscillations
Collective electron oscillations at ω_p = √(n_e e²/ε₀m_e): animated δn wave, Bohm–Gross dispersion ω(k), and ω_p vs density.
Alfvén Wave on a Magnetic Field Line
Transverse MHD Alfvén wave: v_A = B/√(μ₀ρ), animated field-line displacement, standing modes and pulse reflections at fixed boundaries.
Magnetic Reconnection (Sweet–Parker)
Toy Sweet–Parker X-point: opposite B-regions, current sheet, inflow v_in ≈ v_A/√S and outflow, Lundquist number S and sheet thickness δ/L.
Parker Spiral Solar Wind
Rotating Sun plus radial solar wind: interplanetary B spirals with tan ψ = Ωr/v_sw, animated field lines (top view), ψ(r) and |B| falloff.
