4M KidzLabs Magnetic Alarm

Build a working door alert and discover how a magnetic switch completes an electric circuit. The 4M KidzLabs Magnetic Alarm turns any bedroom, cupboard or treasure box into a protected zone.

• Pre-assembled sound unit with wires
• Magnet and switch plate
• Mounting materials and illustrated instructions

While assembling the device children encounter the principles of attraction, poles and closed circuits, all without soldering. Clear step-by-step drawings guide young makers from start to finish.

Ideal for ages 8 years and up. Two AA cells are required (not included). Small parts; adult supervision recommended.

Attach the slim module to a door or drawer—when the magnet moves away, the buzzer sounds and intruders are caught!
