Electromagnet

Description

This amazing electromagnet is like an electric version of the Magdeburg Hemisphere but the resistance to pulling it apart is from the magnetic field generated by 1.5V batteries! Complete with a large easy to hold handle and safety catch to stop excessive backward body motion, students can discover that up to 60 kg of force from a few batteries is a powerful thing. Batteries included, maximum load 60 kg, 270 x 80 mm, 1.4 kg.
