idealMHD
Ideal magnetohydrodynamics (ideal MHD) is a fluid model for conducting plasmas that assumes infinite electrical conductivity, neglecting resistive dissipation. In this limit the magnetic field is frozen into the moving fluid, so magnetic flux through any material loop is preserved (flux freezing).
The model combines fluid dynamics with electromagnetic effects under the assumption of negligible displacement current. The
Key consequences and phenomena of ideal MHD include the Alfvén speed vA = B/√(μ0ρ), which sets characteristic
Limitations and context: ideal MHD neglects resistivity, viscosity, Hall effects, and magnetic reconnection, all of which
