Below pull force calculators are applicable for the magnetic material with straight B-H curve, include sintered Neodymium magnets , sintered Samarium Cobalt magnets and ferrite magnets. The objective was to accurately and repeatedly measure the maximum pulling force that needs to be applied for two magnets to be separated. Modeling the magnetic shield as a plate instead of the whole 3D object saves time. The attractive force F z (z) of permanent magnets centered to each other (x = 0) as a function of their normal distance z was measured with the tensile testing machine Z 5.0 from ZwickRoell, Germany. The other magnet needs to be pulled away in a perpendicular manner. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.

A magnets magnetism passes through non-magnetic materials. For direct contact select fixed distance 0. These pull force values are presented to aid in design but the user should not use them as a definitive reference: The diameter of a magnet has a great influence on its pull force, and the relationship is linear. "variable": Calculation carried out for 10 different distances. This calculator computes the force between a solenoid and another piece of ferromagnetic material separated by a gap of distance g. F = (Fm) 2 0 A / (2 g 2) F = (N*I) 2 0 A / (2 g 2 ), Where: 0 = 410-7. W = ( B 2 / (2 0 )) (g A) Equation FRT. The measuring device records the pounds pull.
