10 mm Samarium-Cobalt (SmCo)
PM-BA-S-SG-D10x4.5
SKU: GM17103
Stock: 18
Holding force: 20 N
Height: 4.5 mm
Material housing: Galvanized steel
Compact flat magnet systems available in neodymium, samarium cobalt, ferrite and AlNiCo. Suitable for gluing. Thanks to the shell of these magnet systems, the magnetic field strength increases and the pot magnets are more resistant to corrosion or chemicals. Pot magnets have a single attracting surface. This precludes dispersion of the magnetic field.The specified holding forces are measured under optimum conditions: perpendicular, on a piece of grade 37 steel that has been ground flat with a thickness of 5 mm, without an air gap.

Deliverable from stock
Available in various sizes
Available with extra strong magnet

Construction of NdFeb pot magnets

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron - (NdFeB) - which Goudsmit markets under the brand name Neoflux®. The shell provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface is covered with a protective coating to prevent corrosion.

Operating temperature

When does loss of magnetic strength occur?

Neodymium cylindrical, flat pot magnets have a maximum operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% of its magnetic force. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.

Important to know

Magnetic short circuit

To prevent loss of holding force due to magnetic short-circuit, neodymium magnets with a brass shell may not be pressed directly into steel. Always maintain a minimum distance between the brass shell of the pot magnet and the steel. Contact Goudsmit for specific recommendations.
