How It Works
This metal detector kit operates on the principle of electromagnetic induction using an oscillator circuit. The search coil generates an alternating magnetic field. When a metallic object enters this field, it disrupts the oscillation frequency due to changes in inductance. This frequency shift is detected by the circuit, which triggers the buzzer and LED to alert the user. The closer the metal object, the stronger the response - providing intuitive, real-time detection feedback.
