The system consisting of permanent magnets of Kittel open domain structure with a mask made of thin sheets of soft magnetic material is described. The simulations showed that the maximal value of induction for system consisting of two neodymium–iron–boron magnets in presence of a mask is increased from 3 T (without a mask) up to 4 T. In this case the product B ∇ B on the distance of 0.01 mm achieves a value of 4.2 × 10 11 mT 2 /m. The experimental device with a mask made of low carbon steel sheets is shown to be useful for separation of paramagnetic substances such as dysprosium sulfate, europium chloride and copper chloride.
