Magnet Crane (electromagnet)
Explore magnets: make a compass and an electromagnet crane. Test distance/turns vs strength. Covers magnetic fields, poles, and electromagnetism.
Recommended for ages 9-12
About This Kit
Build a floating compass and a coil‑and‑core electromagnet crane, then test lift vs coil turns/current/distance. Map field lines and relate compass behavior to Earth’s field. Covers magnetism, electromagnetism (field ∝ turns×current), and practical applications in sorting/lifting. Emphasizes fair testing and safety with batteries and coils.
