Q. How can you tell if a whiteboard is magnetic?

Answer

If needing to make a glass marker board magnetic need to add a backing. Therefore if the whiteboard doesn't have a steel back or porcelain face it isn't magnetic. Medium-density fiberboard (or MDF) and particleboard are the two most common materials used in the production of non-magnetic whiteboards. In comparison to particleboard which is predominantly composed of sawdust medium-density fiberboard (MDF) is made of pressed wood fibers. Both are commonly used in low-cost cabinets and mass-produced furniture so probably encountered them already. Manufacturers can keep costs down by using either of these materials which is great news for anyone looking for an affordable dry-erase board.
