... If an object loses electrons, it is left with more protons than electrons. This means it will have a positive charge If an object gains electrons, it now has more electrons than protons This means it will have a negative charge ...

Lecture 4: Boundary Value Problems
... So far, we considered fields in an infinite space. In practice, however, we often encounter situations when fields live in a finite space consisting of bounded regions with different electromagnetic properties. ...

... the objects (i, ii, iii, iv) shown in Fig. 5. (a) Assuming each object carries charge with uniform density 400 nC/m3 throughout its volume, find the charge of each object. (b) Assuming each object carries charge with uniform density 15.0 nC/m2 everywhere on its exposed surface, find the charge on ea ...

... where time interval is to be taken in the sense of the definition in § 1. Let there be given a stationary rigid rod; and let its length be l as measured by a measuring-rod which is also stationary. We now imagine the axis of the rod lying along the axis of x of the stationary system of co-ordinates, ...

Holy Cow Magnet!
... filings seem to arrange themselves in a pattern of lines that loop from one pole of the magnet to the other. That's because each tiny iron shaving was temporarily magnetized by the magnet. Iron is a material that becomes magnetized in the presence of strong magnets which is why magnets attract iron. ...
