What stud pot magnet sizes
|
||||
 |
Stud pot magnets are always measured diameter x depth. The size always includes the shell within the measurements. | |||
Diameter |
||||
 |
The diameter refers to the distance between the two widest points of the stud pot magnet. It ranges from 10mm (0.39″) to 125mm (4.9″). | |||
 |
The diameter you choose will depend on where the stud pot magnet is going to be used.
For example, if the magnet is going to be used for promotional ceiling signs or light fittings, the diameter should be larger, as the magnet needs greater contact with the ferromagnetic material to provide a secure hold. |
|||
Depth |
||||
 |
The depth of a stud pot magnet is the distance from the top of the stud to the magnetic face, and can range from 5mm (0.2″) to 70mm (2.8″). | |||
 |
The depth you choose will depend on the amount of space available for the stud pot magnet. If there is a limited height available, then a magnet with a depth of less than 20mm (0.79″) would be ideal. | |||
Magnetic pull |
||||
 |
The magnetic pull of stud pot magnets ranges from 0.8kg (1.8lbs) to 164kg (361.56lbs). | |||
 |
The magnetic pull is the maximum weight of ferromagnetic material the stud 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 |
||||
 |
To summarise, when purchasing a stud pot magnet, the key thing to look out for is the depth and diameter. These affect the tool’s ability to hold non-ferromagnetic material to a ferromagnetic surface (e.g. a down light to a steel ceiling). | |||
