What is meant by spatial gradient?

The term “spatial gradient magnetic field” refers to the rate at which the static magnetic field strength changes over space or distance per unit of length. This parameter is indicated as dB/dx, using the units of T/m or gauss/cm.

What is the definition of a gradient?

gradient. noun. gra·​di·​ent ˈgrād-ē-ənt. : change in the value of a quantity (as temperature, pressure, or concentration) with change in a given variable and especially per unit on a linear scale. : a graded difference in physiological activity along an axis (as of the body or an embryonic field)

Why are we interested in maximum spatial gradient?

Why is it important? The attractive force experienced by a ferromagnetic object in the field of the scanner is dependent on the spatial gradient. The larger the spatial gradient, the larger the force on the object.
