The unit of Inductance is Henry and formula to measure the Inductance is: L = (μ ο * N 2 * A) / l Now according to Faraday's law, because of this Electric field, a voltage develops across the coil which opposes the change in magnetic field and that’s how Coil develops the Inductance, means the generated voltage opposes the increase in the current. And the change in the magnetic field generates an electric field. Whenever some current passes through the coil, it generates a magnetic field around it. All these components should be easily available in your local hardware shop.
The following are the components that you would need to build a simple DIY metal detector using Arduino.
Wherever this detector detects any metal near it, the buzzer starts beeping very rapidly. This is very interesting project for all electronics lovers. Here we have used an Arduino Nano to build this metal detector project. In this project, we are going to use a coil and capacitor which will be responsible for the detection of metals. Previously we have made a very simple Metal detector without a microcontroller, now we are building the Metal Detector using Arduino. Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas, etc.
