= Nonmonotonic magnetic bending
For nonzero imposed surface inclination, <magnetic bending in an incompressible disk> is nonmonotonic when $KH>\pi/2$: the first maximum of $|B_x|$ occurs at $z=\pi/(2K)<H$, followed by a decrease. This is exactly the <finite-thickness magnetorotational instability criterion> for the same slab. The zero-inclination equilibrium can still be unstable, so nonmonotonic bending is a property of the forced profile, rather than a condition on every possible unstable equilibrium.
