The Kraul Magnetism Experiment Kit is a hands-on STEM science kit that invites children to explore the invisible forces of attraction and repulsion through a series of simple, engaging experiments. Young scientists can create magnetic pendulums, compasses, and even a chain of nails — and using iron filings, they can reveal the hidden patterns of a magnetic field, making the invisible forces of physics wonderfully visible. The kit also introduces the concept of an electromagnet — a special type of magnet that can be switched on and off — offering a playful and practical gateway into the science behind many everyday technologies. A thoughtful choice for home education, science projects, and children with a curiosity for physics and engineering. Why We Love It The iron filings experiment is particularly special — there's a real gasp-out-loud moment when those invisible forces suddenly reveal themselves as something you can actually see and trace. The electromagnet element introduces a concept that genuinely surprises most children — the idea that a magnet can be turned on and off feels almost like a superpower, and that sense of wonder is exactly what good science should spark. This is a kit that rewards patience and careful observation, making it a wonderful choice for a child who enjoys slowing down and really investigating how things work.
