Guess which objects are magnetic? That?s the fun (and the learning!) behind our Magnetic Discovery Board. Objects are randomly arranged in the 16 wells of this wooden board for residents to predict and observe magnetic properties. The tough acrylic cover can be removed by staff to switch objects out then screwed back in place to lock them in. Magnetic Wands (074864), not included. Board measures 23 H x 30.5 W x 2cm D.
