of a magnetic separator to lift a particular mineral is dependent not only on the value of the field intensity, but also on the field gradient, which is the rate at which the field intensity increases towards the magnet surface [6]. Production of a high field gradient as well as high intensity is therefore an important aspect of separator design.
