Basic magnetic discs are always measured diameter x depth.
The diameter refers to the distance between the two widest points of the basic magnetic disc. It can range from 1mm (0.039″) to 127mm (5″).
The depth of a basic magnetic disc is the distance between its two magnetic faces and can range from 0.25mm (0.0098″) to 11mm (0.43″).
The magnetic pull of a basic magnetic disc ranges from 0.02kg (0.44lb) to 45kg (55lb).
Different sizes of basic magnetic discs can be used for a large array of different applications. Large basic magnetic discs, for example, can be used for a robotics motor. There are two basic magnetic discs on either end of the motor for acceleration and changing direction.
A small basic magnetic disc, however, is more beneficial for activities such as model making, as it can be attached inside a small figurine without being visible to the user, making it more aesthetically pleasing.
