It is a round magnet with a diameter of 40 mm (1.57\") and a height of 4 mm (0.16\"), magnetised axially through its height, so the two round faces are the north and south poles. It is a practical size for closures, displays, holding tools and panels, jigs and fixtures, and prototype or model work.\u003c\/p\u003e\u003cp\u003eN48 is one of the higher grades of neodymium and gives a high holding force for its size (N50 and N52 are stronger still). The holding force is highest when the magnet sits directly on a thick, flat steel plate; it is lower on thin or painted steel, on rough surfaces or with an air gap.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDimensions: Ø 40 x 4 mm (1.57\" x 0.16\"), magnetised through the 4 mm (0.16\") height\u003c\/li\u003e\n\u003cli\u003eGrade N48 neodymium (NdFeB) with nickel coating (Ni-Cu-Ni)\u003c\/li\u003e\n\u003cli\u003eMaximum operating temperature 80 °C (176 °F)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe nickel coating protects the magnet against corrosion in dry, indoor conditions.
