Magnetic Field Specification of Magnets

Click For Summary
SUMMARY

The magnetic field specification of magnets is often indicated by a tesla rating, such as "0.2" Tesla, which typically represents the strength of the magnetic field measured at or near the center of the pole surface. This rating may vary based on the manufacturer's standards and the intended application of the magnet. Users should consider these specifications as general guidelines for comparing different magnets, as detailed explanations are usually provided by manufacturers regarding the meaning of various specifications.

I'm not sure where else to post this.

How are magnets specified? If a magnet is "0.2" Tesla, is that the maximum magnetic field present at the surface?
 
Engineering news on Phys.org
Magnets are specified however the manufacturer or retailer wants to.
A lot will depend on the intended use of the magnet.

Often, a tesla-rating for a permanent magnet is the strength of the magnetic field measured at or very close to the center of the pole surface ... or averaged over the surface.

You usually only want them as a rule-of-thumb for comparing magnets.
Manufacturers will usually supply information about what the various specifications mean.
