Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also push other magnets away. So how come you feel only the pull of gravity? In 1915, Alber...

Ferrous metal is defined as any metal that contains iron. Ferrous metals are very common due to the heavy use of iron in most metal alloys. Ferrous metals contain a large enough iron content to create enough domains for a magnetic field to act on and attract. Ferrous materials are the only...
Why are metals good conductors of heat and electricity? Why would electrical engineers or electricians be interested in conductors and insulators? Why is rubber an amorphous solid? Why is epithelial tissue important? Why does touching the ground neutralize a conductor?
However, if it is strong magnetic, it is composed of rare earth metals such as cobalt, boron, europium, iridium and other compounds. So it's all white. The common magnet material is Fe3O4 and Fe3O4 is black, so the common magnet is black....
such as kilonovae, variable stars, or Type Ia supernovae, among others. Scientists using one of Rubin’s community systems, like Fink, will be able to sort the massive dataset of alerts according to selected filters, allowing them to quickly home in on the data that are useful for ...
each suited for different materials and welding conditions. The electrode's composition, coating, and diameter all play a role in the welding process. For instance, low-hydrogen electrodes are preferred for critical applications to minimize the risk of hydrogen-induced cracking. To knowTungsten Electr...

By analyzing magnetic and electric crystal barrier properties Siltech’s engineering group found that contaminants of certain metals have a profound effect on musical performance. Quite large amounts of certain materials can be rather benign, while even tiny amounts of others can be extremely intrusive...
Magnets are materials that produce magnetic fields, which attract specific metals. Every magnet has a north and a south pole. Opposite poles attract, while like poles repel. While most magnets are made from metals and metal alloys, scientists have devised ways to create magnets from composite mat...
