30+ Electricity & Magnetism Projects

This Butterfly EduFields STEM kit provides 30-plus hands-on experiments covering electricity and magnetism. Children aged 8 to 14 can build working models such as an electromagnetic crane, electrolysis setup, electroplating bath and a DC motor. The set includes over 100 components including wires, bulbs, switches, connectors and LED lights. A step-by-step illustrated manual guides every build.

For curious learners aged 8-14

The kit suits boys and girls who want screen-free science play and enjoy building functional electrical circuits. It fits home learning, school projects or birthday gifts for the 8-to-14 age range. Buyers needing advanced robotics, coding platforms or autonomous sensor-driven models should consider a different product line. This set focuses on fundamental electromagnetism principles only.

Requires two AA batteries (not included)

Every project in the box needs a two-cell AA power source that must be purchased separately. Without these batteries no circuit will operate and the 30-plus experiments cannot be completed. Ensure a fresh pair is on hand before the first build session begins.

Questions about this item

How do I install the 2 AA batteries required for the 30 projects, and what step do people get wrong?

Insert two AA batteries into the battery holder following the polarity markings, then secure the cover; the common mistake is reversing the positive and negative ends, which prevents the circuits from powering up.

What maintenance or replacement will the kit need after repeated use?

The 2 AA batteries will need replacing when they no longer power the LED lights and motor; the 100+ wires, bulbs, switches and connectors are reusable and only require checking for loose connections.

What limit appears first during sustained use of the electromagnetic crane or motor projects?

The 2 AA batteries drain fastest under continuous motor or electrolysis loads, so project run time is limited by battery capacity rather than the components themselves.
