It is magnetised through its 2 mm thickness, so the two 20 x 4 mm faces are the north and south poles. Its small size makes it easy to build into models, packaging and box closures, displays, sensors, craft projects and small DIY builds.\u003c\/p\u003e\u003cp\u003eN45 is a high grade of neodymium that gives strong holding force for its size (grades N48 to N52 are stronger still). The calculated pull force is approx. 2 kg when the magnet sits directly on a thick, flat steel plate. In practice the force is lower on thin or painted steel, on rough surfaces or with an air gap.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDimensions: 20 x 4 x 2 mm, magnetised through the 2 mm thickness\u003c\/li\u003e\n\u003cli\u003eGrade N45 neodymium (NdFeB) with nickel coating (Ni-Cu-Ni)\u003c\/li\u003e\n\u003cli\u003ePull force approx. 2 kg (calculated estimate)\u003c\/li\u003e\n\u003cli\u003eMaximum operating temperature 80 °C\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe nickel coating protects the magnet against corrosion in dry, indoor conditions.
