Metal detectors for searching metals in the ground

AI Thread Summary
Metal detectors function by using electromagnetic fields to detect metal objects buried in the ground. Frequencies around 8 kHz are commonly used in metal detectors, and there are no significant health risks associated with this frequency; the primary concerns are related to environmental hazards, such as being unaware of surroundings while searching. Key characteristics of a metal detector include sensitivity, discrimination capabilities, and depth detection, which determine its effectiveness in locating different types of metals.

Metal detectors for searching metals in the ground

How they work in one sentence explanation?

and second,
I've seen some frequency of about 8 kHz mentioned,could that be any possible health risk?

Please discuss, thanks.

Welcome to the PF.

You can find that info with just a little searching via Google or other similar websites. Here is a basic introduction with other links:

http://en.wikipedia.org/wiki/Metal_detector

Let us know if you have any specific technical questions after you read the introductory material.
 
The only health risk is that you can get run over by cars while not paying attention to where you are walking.

I'm totally serious.

That and a bad sunburn on the back of your neck.
 
admin Borek you can easily delete this whole thread, no problem

i'd like to ask also what would be the most important characteristic/function of a metal detector?

Why do I have a feeling you are trolling?
 

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
