Web1 de mar. de 2024 · 3. Relaxation under the constraint of conserved helicity. The conserved magnetic helicity places a lower bound on the magnetic energy M { B 2 } = 1 2 ∫ B 2 d V of a localised magnetic field, as recognised by [2]. Suppose that the magnetic field is located in a fixed domain D of length-scale ℓ, with n ⋅ B = n ⋅ v = 0 on the boundary ∂ D.
