When the magnetic field of the coil moves across metal, such as the coin in this illustration, the field induces electric currents (called eddy currents) in the coin. The eddy currents induce their own magnetic field, shown in red, which generates an opposite current in the coil, which induces a signal indicating the presence of metal. As you can probably tell metal detectors are very useful not only to find that cherished earring but for our everyday safety and well being. This is a great invention that will be here for years to come. The metal detectors in airports, office buildings and prisons for example help ensure that no one is bringing a weapon onto the property. Consumer oriented metal detectors provide entertainment to people and give chance in discovering hidden treasures. Metal detectors work on the principal of electromagnetism and their effects on conductive metals. The high-powered coil of metal, called the transmitter, uses the battery power to generate a penetrating magnetic field. As the electromagnetic field enters the ground, anything metallic will become charged with magnetism. Tips for Metal Detecting Buying a metal detector is just the first step in a persons' quest to look for old coins and jewelry. Before going on that expedition, here are a few tips worth knowing that will help make the search successful. 1. People who don't know how to use a metal detector should learn from those who know how to use it. This will make it easier for the user to know when there is something worth digging or just ignoring and continue on with the search. 2. Before going out, the metal detector should be checked to make sure it is functioning properly. The best way would be to hide a coin in the garage and have the individual successfully find it; this will increase the chances of finding other artifacts during the treasure hunt. 3. Another thing that has to be checked is the weather. Tests have shown that looking for objects when it is snowing or raining outside is useless because these interfere with the instruments on the metal detector. This means the person will have to wait until the conditions outside improve or reschedule the search when it is sunny. Youve got to buy a metal detector that could withstand normal wear and tear longer than its competitors. The longer the metal detector
