About the Product
Neodymium tube magnets provide an ID/OD geometry with defined wall thickness for shafts, pass-through fasteners, and flow-through fixtures. Axial magnetization through thickness yields a clean annular field; diametrical options are available for certain sensing applications. Tight ID/OD and length tolerances support press-fits and concentric mounting with minimal runout. Use the calculator to model attraction versus steel and air gap, then size grade and coating using the material data to meet field and temperature targets.
