K120-3 Electrical Circuit & Electromagnet Science Kit

💡 Build a Working Circuit | 🧲 Explore Electromagnetism | 🔬 Hands-On Science Learning

Overview

Turn scientific curiosity into hands-on discovery with the K120-3 Electrical Circuit & Electromagnet Science Kit. This educational set introduces basic electricity and magnetism through two practical experiments: lighting a miniature bulb and building an electromagnet that attracts paper clips.

With a battery holder, bulb, switch, connecting components, copper wire, and an iron nail, learners can assemble simple experiments and observe how they work. It’s an engaging choice for supervised home learning, classroom demonstrations, and school science projects.

Key Features

Build a Working Electrical Circuit
Connect the battery, wires, and bulb holder to discover how a complete circuit allows the miniature bulb to light up.

Explore Electromagnetism
Wrap the supplied copper wire around the iron nail and connect it to the battery to explore how electricity can create a magnetic effect.

Discover How a Switch Works
Use the included switch when assembling circuits to understand how opening and closing a circuit controls the flow of electricity.

Practical Learning with Real Components
The separate components encourage learners to assemble, observe, and investigate rather than simply watch a demonstration.

Supports School Science Projects
Use the kit to demonstrate basic scientific principles, draw circuit diagrams, and record observations for educational activities.

Experiment Instructions Included
Instructions printed on the back of the packaging introduce the bulb-lighting and electromagnet experiments.

Why You’ll Love It

The K120-3 makes introductory science tangible. Lighting a bulb and attracting a paper clip with an electromagnet give learners visible results they can connect to the components they assembled. Its straightforward experiments encourage curiosity, observation, and a better understanding of how simple electrical systems work.

Care & Use: Adult supervision is recommended. Disconnect the battery after each experiment, avoid connecting its terminals directly together, and disconnect immediately if a wire or component becomes warm. Keep small parts away from young children.
