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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Pre-printed PCB (labeled component layout)\u003c\/li\u003e\n\u003cli\u003e1 x Inductor Search Coil\u003c\/li\u003e\n\u003cli\u003eTransistors (as per circuit design)\u003c\/li\u003e\n\u003cli\u003eCapacitors (electrolytic and ceramic, assorted values)\u003c\/li\u003e\n\u003cli\u003eResist\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eProducts ship within 1-5 days from our Bengaluru warehouse.
