Magnetic Field Model in Acrylic Box
by American Scientific

Comprised of 117 magnetic needles that have been mounted at equal distances from each other inside a sturdy acrylic box, the magnetic field model helps to visually demonstrate the magnetic fields that are produced by a magnet. The clear acrylic box makes it perfect for use with an overhead projector. It comes complete with a teacher’s guide that features a suggested lesson plan that can easily be built off of or incorporated into an already existing teaching lesson.
