Surface rating of Magnets

Surface Gauss

Surface gauss refers to the gauss measurement-at the surface of a magnet. Magnets can have vastly different strengths between the center of the magnet and its surface. The surface gauss rating is an accurate tool to be used to determine how strong the magnet will really be when it is used.

Scientists who utilize gauss ratings will default to the surface gauss when recording the strength of a magnet. General ratings of magnets are likely to use surface gauss, but it is rare for a seller of magnets to use surface gauss when listing the strength rating of a magnet.

The magnetic field that is affected by a magnet will be impacted by the surface gauss rating of the magnet. Some manufacturers are able to provide information about the surface gauss of a magnet when asked.

Manufacturer's gauss

Manufacturer's gauss refers the gauss rating of the internal portion of the magnet. This rating is typically higher than the surface gauss. It is possible for the internal gauss of a magnet to be higher than the actual gauss of the magnet.

Another name for manufacturer's gauss is magnetic resonance. The gauss rating that is quoted by a manufacturer is a reading of the strength of the magnet at its core.

It is important for buyers to understand the difference in gauss ratings in order to ensure that they purchase a magnet that is strong enough for their needs. While it may appear that the manufacturer's gauss rating is deceptive in nature, the truth is that manufacturers simply use a rating system that strives to represent the strength of the strongest part of the magnet.

When you are in doubt about which gauss rating to use, you should assume that the rating relates to the manufacturer's gauss. However, getting a magnet for a project is a matter of making sure that the gauss rating is accurate. Buyers can contact the manufacturer or the seller for clarification when the strength of a magnet is particularly important.
