Strontium Ferrite Pot Magnet, Diameter: 36 mm, Externally Threaded
 
The pot magnet is a magnet assembly containing a permanent magnet in a steel housing. The housing partly closes the magnetic circuit and directs flux from the pole towards the contact surface, improving holding force in direct contact compared with a bare magnet. Ferrite (strontium ferrite) is a ceramic magnetic material with good resistance to corrosion and stable properties. With a pot housing, it provides a secure industrial attachment point. The external thread makes installation simple: screw it into the mating component to create a magnetic attachment point. (Quick specifications: D = 36 mm; H = 8 mm; L = 19 mm; thread: M8; Tmax: 200 °C)
 
Paint, film, surface roughness and any air gap reduce flux and holding force. A pot magnet performs best in direct contact with solid steel. Typical uses include assembly aids, temporary attachments, labels and signs, simple holders and workshop positioning. For applications involving heat, use the Tmax value as the limit. Ferrite generally tolerates heat well, but observe the limits of the assembly.
 
Warning: technical product. Bring magnets together and separate them carefully. Avoid impacts and keep away from electronics and medical devices.
