Abstract
We present the theory of quasiparticle transport in perturbatively small inhomogeneous magnetic fields across the ballistic-to-hydrodynamic crossover. In the hydrodynamic limit, the resistivity generically grows proportionally to the rate of momentum-conserving electron-electron collisions at large enough temperatures . In particular, the resulting flow of electrons provides a simple scenario where viscous effects suppress conductance below the ballistic value. This new mechanism for resistivity in a Fermi liquid may describe low transport in single-band .
