What bi-pole pot magnet sizes
are available?

Diameter and depth of bi-pole pot magnet Bi-pole pot magnets are always measured diameter x depth. The size always includes the shell within the measurements.

Diameter

Diameter of a bi-pole pot magnet 6mm and 32mm The diameter refers to the distance between the two widest points of the bi-pole pot magnet, and ranges from 6mm (0.24″) to 32mm (1.26″).
The diameter you choose will depend on the size of the fixture or jig you are creating. If you are creating a small jig or fixture, then you may require a bi-pole pot magnet with a smaller diameter, to make the fixture or jig more slimline.

Depth

Depth of a bi-pole pot magnet 20mm and 40mm The depth of a bi-pole pot magnet is the distance between the top of the shell and the magnetic face. It can range from 20mm (0.79″) to 40mm (1.57″).
Depth of wood The depth you choose will depend on the depth of the non-ferromagnetic material you are attaching the bi-pole pot magnet to.

If you are creating a jig out of wood with a 20mm (0.79″) depth, then you could use a bi-pole magnet with a 20mm (0.79″) depth, however you will not be able to use a 40mm (1.57″) depth bi-pole magnet as this will be too large.

Magnetic pull

Magnetic pull of bi-pole magnet 71.4kg and 1kg The magnetic pull of bi-pole pot magnets ranges from 1kg (2.2lbs) to 71.4kg (157.4lbs).
Neodymium magnet elements: Neodymium Nd, Iron Fe, and Boron B The magnetic pull is the maximum weight of ferromagnetic material the bi-pole pot magnet can hold. This is not determined by its overall size, but the material the magnet is made from. This means that a large magnet does not necessarily have a larger magnetic pull than a small magnet.

Summary

Diameter and depth of bi-pole pot magnet To summarise, when purchasing a bi-pole pot magnet, the key thing to look out for is the depth and diameter as these are determined by the size of the fixture or jig you intend to use.
