When electricity flows through the transmitter coil, it creates a magnetic field all around it. If you sweep the detector above a metal object (such as this old gray spanner), the magnetic field penetrates right through it. The magnetic field makes an electric current flow inside the metal object. ....etc

report on metal detector of 557 from vegakit

Metal Detector Project

This circuit is most useful for security checking. Metal Detector available in the market are quite expensive.

This metal detector can be used to detect slightly big size metallic objects. It used a sensing coil. This coil should be kept near metallic objects for detection. Input of Circuit is a week colpitt s R.F. range Oscillator. Sensing coil forms parts of tuned oscillator.

When coil is brought near a metallic object magnetic energy is observed and Oscillator fails to ....etc

Remote controlled metal detecting Robot with the remote transmitting images
SUMMARY
Path Finder was sent to Mars in 1998, it was a great achievement, which discovered the secrets of the Mars. This project deals with the RF controlled robot. It is a prototype of a robot for Finder Path.
This robot is controlled by the RF remote control. It can be moved forward and backward Motors Use 60 min. In addition, this robot can take a sharp left and right to development of the chips. This project uses a AT89S52 programming the MCU as STIs. high sensi ....etc

Abstract:
This magnetic impulse interacts with any passing object. But it can pick up magnetic pulses sent by other objects.1-Summary Metal detectors are machines of fascination. Sometimes though. Many of the people who use them are as enthusiastic about extolling the virtues of their favorite metal detector as it comes out in search of a buried treasure. The transmitting coil has an electric current that passes through it. There are two rings: an external coil called the transmitter coil and an internal coil called the receiving ....etc

A metal detector is an electronic instrument that detects the presence of metal near. Metal detectors are useful for finding hidden metal inclusions inside objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe that can be swept over the floor or other objects. If the sensor approaches a metal part, this is indicated by a changing tone on the headphones or a needle moving over an indicator. Usually, the device gives some indication of the distance; The closer the metal is, the higher the pitch in ....etc
