Magnetic field gradient is necessary to attract a piece of iron. As iron is lump collection of magnetic dipoles, its force will be F = ∇(m ∙B ) F → = ∇ ( m → ∙ B →), if magnetic field is uniform, no gradient will be present, so it will not move to neither direction. More intuitive explanation can be made.Web
