Gold detectors work by emitting electromagnetic signals into the ground. When these signals encounter a metal object, such as gold, they create a magnetic field around the object. The detector then picks up this magnetic field and alerts the user to the presence of gold underground.

How does a gold detector work to detect the presence of gold in the ground?
A gold detector works by sending out electromagnetic signals into the ground. When these signals encounter gold, they are reflected back to the detector, which then alerts the user to the presence of gold. This process is based on the principle that different materials reflect electromagnetic signals in different ways, allowing the detector to distinguish between gold and other substances in the ground.
Can catalytic LEL gas detector work in nitrogen atmosphere?
No, catalytic LEL gas detectors rely on the oxidation of flammable gases in the presence of oxygen to produce a signal. Nitrogen does not support combustion, so the detector would not be able to accurately detect flammable gases in a pure nitrogen atmosphere.
What is the science behind using co2 detectors?
Well the science behind using carbon dioxide is kinda simple! Why are they made? To catch people like asylum-seekers and refuges who are doing bad. They detectors sense carbon dioxide. Carbon dioxide is science so you have to explain about carbon dioxide and respiration. We give out co2 afta breathin in oxygen right? well that's science! there you go quite simpal init..?!Read more: http://wiki.answers.com/The_science_behind_using_carbon_dioxide_detectors#ixzz1BQAvvGlzwhat is the science behind using co2 detectors
How is gold mined?
Once gold was discovered in an area, miners rushed to stake a claim to a piece of land to work on. Where gold was present in the beds of creeks or rivers, miners used the panning method to wash gravel until only the heavier gold remained. A similar, better method was to use a rocking cradle to separate gold from worthless stone. They rocked gravel and water in the cradle, sifting out lighter materials and leaving gold. Puddling was another version of panning. Huge tubs or vats, often worked by horses, were used to wash gold-bearing soil. In areas where water was scarce, alluvial gold was mined by dry blowing--that is, miners separated gold from sand by dropping the material from a height and allowing the wind to blow the lighter material away. Once surface deposits were exhausted, miners had to sink shafts into the ground. They tried to follow the line of lode--that is, the gold in quartz veins living and travelling conditions on the goldfields of the 1800's were extremely rugged. Often there were no buildings for shelter. Miners encountered worse conditions as they travelled farther from civilization. Many miners returned home after a brief, unsuccessful, period on the goldfields. Very few made the fortune of which they had dreamed when they set out. Miners came to the goldfields from all parts of the world. For example, many Chinese miners migrated to California during the 1849 gold rush. Later, many of these Chinese miners moved to Australia and New Zealand.
How would you use the gold block to determine the atom radius of an atom of gold?
To determine the atom radius of gold, you can measure the volume of the gold block and then calculate the number of atoms in the block using Avogadro's number and the molar mass of gold. From there, you can calculate the radius by assuming the gold atoms are arranged in a cubic or face-centered cubic structure within the block.
Do crowcon gas detectors work with carbon monoxide?
Crowcon does have gas detectors that will detect carbon monoxide. The detector will send out a signal to warn your household that there is a dangerous amount of carbon monoxide.
What is used to detect gamma rays?
Scintillation detectors, semiconductor detectors, and Geiger-Muller tubes are commonly used to detect gamma rays. These detectors work by measuring the ionizing radiation produced when gamma rays interact with matter.
Where is gold extracted?
Gold is extracted from the earth itself, near the place underground where coal miners work.
What are the detectors of visible light waves?
Detectors of visible light waves include photodiodes, photomultiplier tubes, and charge-coupled devices (CCDs). These detectors work by converting incoming photons into an electrical signal that can be measured and analyzed. They are commonly used in cameras, sensors, and scientific instruments to detect and capture images or quantify light intensity.
How do cobra radar detectors work and who uses them?
Cobra radar detectors are devices used to detect if the police are monitoring your car or checking your speed limit using a radar gun. This is used by motorist so they can fix their speed before getting pulled over.
How can a metal detector detect platinum since it isn't magnetic?
no because platinum has no magnetic field :):):) yeah it sure does Metal detectors work by creating a magnetic field in the coil and then sensing the change in current when a conductor enters that field. Platinum is an excellent conductor and if your metal detector is unable to detect a platinum nugget, try twiddling the sensitivity knob. If it still doesn't work, take it back to the store and exchange it for one that works.
What is the average temperature of the water at the ma in hot springs?
Metal detectors have been a staple of airport security for decades. These tall, boxy metal detectors are meant to be walked through and, theoretically, they will detect any metal objects that pass through them. However, if this was the case, then there wouldn't be any need for the hand-held metal detectors that travel authority agents and security guards usually have. Knowing how the larger metal detectors work, and their failings, can help take the confusion out of any misunderstanding.
Where do people who dig silver and gold work?
People who dig silver and gold typically work in mines or mineral exploration sites. These can be underground mines, open-pit mines, or placer deposits where the precious metals are extracted from the earth.
Where did the least fornunate of Egyptian Slaves work?
The most unfortunate slaves were those who were sent to work in the gold mines. Naked slaves worked for long hours in fearsome heat deep underground hacking out the rock which contained the veins of gold.
How can humans detect infrared waves and what are the methods used for detecting them?
Humans cannot naturally detect infrared waves, as they are beyond the visible light spectrum. However, infrared detectors and sensors can be used to detect infrared waves. These devices work by converting infrared radiation into an electrical signal that can be interpreted by humans. Common methods for detecting infrared waves include thermal imaging cameras, infrared thermometers, and infrared sensors.
Will a metal detector pick up White Gold?
Mention the words metal detector and you'll get completely different reactions from different people. For instance, some people think of combing a beach in search of coins or buried treasure. Other people think of airport security, or the handheld scanners at a concert or sporting event.The fact is that all of these scenarios are valid. Metal-detector technology is a huge part of our lives, with a range of uses that spans from leisure to work to safety. The metal detectors in airports, office buildings, schools, government agencies and prisons help ensure that no one is bringing a weapon onto the premises. Consumer-oriented metal detectors provide millions of people around the world with an opportunity to discover hidden treasures (along with lots of junk). ­In this article, you'll learn about metal detectors and the various technologies they use. Our focus will be on consumer metal detectors, but most of the information also applies to mounted detection systems, like the ones used in airports, as well as handheld security scanners.
If I disconnect one smoke detector, will the other smoke detectors still work?
Yes, the other smoke detectors will still work if one is disconnected. Each smoke detector operates independently and is not interconnected with the others.
