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...
In fact, ordinary micromagnetism (or weak magnetism) is made up of ferrous metals (usually iron and its compounds), so it is black. 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....
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?
It’s strong, environmentally resilient, visually appealing, affordable, and has properties that are hard to come by in other metals. It is a green material due to its near-infinite recyclability. From the surface of the latest kitchen appliance, to a structural beam in a building, to ...
are created by running an electrical current through a conductive metal. An electrical current causes the rapid movement of electrons, which creates a magnetic field. Electromagnetic fields can be created by running an electrical current through any metal, including non-ferrous conductive metals. ...
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...
Why do you use a coil in a magnetic field? Why are cadmium and zinc considered as transition metals? Why is a photodiode more sensitive that a photoresistor? Good thermal conductors are also good electrical conductors. If so, why don't the connecting wires that are used to connect heate...
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...
Covalent compounds : The chemical bond by the sharing of electrons between two atom is known as a covalent bond. Fthe molecules formed by sharing of electrons between two or more same atoms or between two or more non-metals are called covalent compounds.
