Metal Detector - Easy Build

Ever wondered if there's buried treasure in your own backyard? Now you can find out for sure with this easy-build metal detector.


Why we love it:



  • You and your family can learn how electromagnets work

  • Kit includes easy-to-follow instructions so anyone over 8 years old can build this

  • Easy screw assembly


How to build it:
1. Build it following instructions
2. Keeping the detector away from metal, adjust the sensitivity of the device until it no longer makes a noise. Now the detector will make a noise when it's near metal, so you can get hunting!


How it works:
When electric current passes through the wire coil, it creates an electromagnet. When passed near a ferrous (or magnetic) metal, for example iron, eddy currents are produced in the metal. This disrupts the magnetic field produced by the coil and causes the buzzer in the detector to go off.


Dimensions: Approx. 18.5cm long x 6.5cm wide (at widest point)
