the energy of light goes to electron movement through electron holes created by raising the energy of the metal in photodetector with the light.
You can build a metal detector using an AM radio and Calculator.But it is not sure that it will work or not.My brother had made metal detector using an AM radio and calculator two months ago,first it doesn't work at all but than he made some changes than it began working.Gurjot Singh Sodhi
Metal is more durable then wood and will last longer. Metal can handle marks or spills better then wood. If you spill liquid on wood it can rot easily
A metal band saw power tool can cut into wood as well as metal. However, the reverse does not work. A wood band saw would not be able to cut into metal.
A homemade metal detector works better over sand. It works the Same both of them but it takes a longer time to find the metal in the soil. Try it at home just grab soil sanda radio and a calculator. Also a piece of metal .
Metal and wood and a little hard work.
PVA is designed to work on porous materials only. It is a wood glue and not for metal
wood work and metal work at school... mainly in high school for boys
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.
A cobra detector is a radar detector. Radar detectors work the same way a radio receiver does. The radar detector looks for frequencies that a radar gun uses.
In a gunsmith's shop. It had equipment for working on metal and wood.
The Hand Held Meter Detector will work with all metals, although some may prove to be more troublesome than others.
