Detailed Description

DC current through an aluminum rod + movable permanent magnet.

Physics: Rod B field – precomputed once via div(sigmagradphi)=0 -> J -> laplacianA=-mu_0J -> B=curlA Magnet – magnetic dipole field, evaluated analytically every frame: B_dip = mu_0/4pi * [3(m*r_hat)r_hat - m] / r^3 (m = M0*y_hat) Total B – B_rod (sampled from grid) + B_dip (analytical)

Controls: LMB drag – orbit camera RMB drag – pan Scroll – zoom Shift + LMB drag – move magnet (horizontal -> XZ, vertical -> Y)
