It is a sphere with a diameter of 30 mm, magnetised through its diameter, with the north and south poles on opposite sides. Spheres are used for magnetic construction and demonstration models, flexible joints, displays and educational projects.\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 calculated pull force is approx. 14 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: Ø 30 mm\u003c\/li\u003e\n\u003cli\u003eGrade N48 neodymium (NdFeB) with nickel coating (Ni-Cu-Ni)\u003c\/li\u003e\n\u003cli\u003ePull force approx. 14 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.

Separate magnets by sliding them apart, never let them snap together, and wear gloves when handling several at once.
