Magnets for glass boards

 Our popular selling magnets for glass

Our bestselling magnets for glass boards are 10x10 mm power magnets. They can be used on all magnetic glass boards, and depending on the quality of the glass board, up to 10 sheets of paper can be hung under this magnet without either the paper or the magnet sliding down the otherwise smooth board.

Glass magnets

Glass magnets – or magnets for glass boards – face the challenge of needing to ‘work’ through a thick layer of glass, which is why very powerful magnets are required for magnetic glass boards. It’s because the glass itself isn’t magnetic; instead, it’s the steel plate behind the glass.

Loss of strength on glass boards

Even though the magnets have very high strength, approximately 70-90% of the strength is lost when there is 2-4 mm between the magnet and the board’s steel plate (i.e. the thickness of the glass plate defines the distance). Glass is great for writing on, but without super strong magnets, you won’t get far in using it as a magnetic board.

Can one choose magnets too strong for glass boards?

Now, we have established strong magnets are needed for glass boards. But they must also not be TOO strong, because they can damage the glass. They will always be attracted to the strongest magnetic field (which in this case is the other magnets and not the glass board itself), leaving you with a big clump of magnets that are nearly impossible to separate – and worse-case scenario, the magnets may also break due to the impact at high speed.

Furthermore, you can cause damage to the glass board and the magnet itself with very hard impacts from the magnet directly against the glass. Therefore, we do not recommend choosing a load capacity of more than 26.5 maximum.
