Glass whiteboards magnets

When customers seek advice on selecting the best magnet for their glass whiteboards, the situation can be challenging due to the varying construction of these whiteboards. Ideally, the glass whiteboard manufacturer would provide guidance on the appropriate magnet strength based on the thickness of the glass and whether the board has a steel backing or uses magnetic paint. However, many customers find that this information is not always readily available.

Typically, glass whiteboards are made with glass sheets ranging from 6 to 10mm in thickness. This creates a significant “air-gap” between the magnet and the magnetic backing, whether steel or magnetic paint. To overcome this gap and ensure sufficient hold, Neodymium magnets (the strongest available magnets) are usually required, as they have a magnetic field strong enough to penetrate the thick glass and reach the magnetic backing.

One important factor to keep in mind is that the magnet’s strength should be carefully controlled to avoid damaging or cracking the glass whiteboard. A magnet that is too strong might attract with excessive force, posing a risk to the glass. Without knowing the exact glass thickness or the specific construction details of the whiteboard, it is difficult to recommend a specific magnet or pull force. Testing a few different magnet sizes and strengths before purchasing in bulk is often a wise approach.
