Iron, for example, has four unpaired electrons with the same spin. Because they have no opposing fields to cancel their effects, these electrons have an orbital magnetic moment. The magnetic moment is a vector— it has a magnitude and a direction. It's related to both the magnetic field ...
While this is happening, the moving electrons also create a magnetic field. If you take the batteries out of your remote, it will likely retain a small magnetic charge. You couldn't pick up a car with your remote, but maybe you can pick up some small iron filings or even a paper clip...
people use it for making steel, automobile frames and parts, building structures and tools. The iron atoms is made of 26 protons, 26 electrons and has 30 neutrons. The atom has four spherical energy levels. The first energy level has three electrons, the second has eight electrons, the thir...
Iron: Iron is a very crucial mineral that is required by the human body. It is essentially needed for maintenance as well as the formation of the blood in our body. Iron helps in the growth of the body and also aids in the development ...

Laser printers also print much sharper lines and are therefore well-suited for text, logos and simple business graphics. The economical laser printers are mostly monochrome, however. Modern inkjet printers print both black and white and color these days, and they have an edge on laser printers ...

When you heat iron, the atoms inside it absorb the heat energy you supply. The electrons inside the atoms push out farther from the nucleus to soak up this extra energy. But this makes them unstable, so they quickly return to their original or "ground" state. When they do so, they ...
When we switch on the power, the copper sulfate solution splits into ions (atoms with too few or too many electrons). Copper ions (which are positively charged) are attracted to the negatively charged brass electrode and slowly deposit on it—producing a thin later of copper plate. Meanwhile...
