Are all metals attracted to a magnet? How does the magnet attract something that is originally non magnetic? The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? Explain how a single magnet can repe...

aall types of metal are detected. However, magnetic metals are detected more reliably than non-magnetic ones. This way of measuring also makes it possible to detect metal particles inside the product or in non-metal packaging. The examined products are not harmed or changed in any way. 金属...
Do you know that gold, silver, platinum and more precious metals are used in the machines a doctor uses to do your MRI and CAT-scan? Do you know the gold that is used in all that technology is 99.9999% pure? Jesus is the “Mess”-enger All that gold is on the inside. You see...

electrostatics can only be used to describe insulating, or dielectric, materials entirely characterized by electric permittivity. When performing an electrostatics analysis, any conducting materials (typically metals) are first removed from the analysis and the metallic surfaces are seen as exterior boundari...
