Thus macroscopic objects tend toward being neutral overall, but macroscopic objects are rarely perfectly net neutral. </p><p>Sometimes macroscopic objects contain ions distributed throughout the material, rigidly bound in place, giving an overall net positive or negative charge to the object. Also, macroscopic objects made of conductive elements can more or less easily (depending on the element) take on or give off electrons, and then maintain a net negative or positive charge indefinitely. When the net electric charge of an object is non-zero and motionless, the phenomenon is known as <a href="/wiki/Static_electricity" title="Static electricity">static electricity</a>.

In this way, non-conductive materials can be charged to a significant degree, either positively or negatively. Charge taken from one material is moved to the other material, leaving an opposite charge of the same magnitude behind. The law of <i><a href="/wiki/Conservation_of_charge" class="mw-redirect" title="Conservation of charge">conservation of charge</a></i> always applies, giving the object from which a negative charge is taken a positive charge of the same magnitude, and vice versa. </p><p>Even when an object's net charge is zero, the charge can be distributed non-uniformly in the object (e.g., due to an external <a href="/wiki/Electromagnetic_field" title="Electromagnetic field">electromagnetic field</a>, or bound polar molecules).

Gilbert hypothesized that this amber effect could be explained by an effluvium (a small stream of particles that flows from the electric object, without diminishing its bulk or weight) that acts on other objects. This idea of a material electrical effluvium was influential in the 17th and 18th centuries. It was a precursor to ideas developed in the 18th century about "electric fluid" (Dufay, Nollet, Franklin) and "electric charge".<sup id="cite_ref-Baigrie11_19-0" class="reference"><a href="#cite_note-Baigrie11-19"><span class="cite-bracket">&#91;</span>19<span class="cite-bracket">&#93;</span></a></sup> </p><p>Around 1663 <a href="/wiki/Otto_von_Guericke" title="Otto von Guericke">Otto von Guericke</a> invented what was probably the first <a href="/wiki/Electrostatic_generator" title="Electrostatic generator">electrostatic generator</a>, but he did not recognize it primarily as an electrical device and only conducted minimal electrical experiments with it.<sup id="cite_ref-20" class="reference"><a href="#cite_note-20"><span class="cite-bracket">&#91;</span>20<span class="cite-bracket">&#93;</span></a></sup> Other European pioneers were <a href="/wiki/Robert_Boyle" title="Robert Boyle">Robert Boyle</a>, who in 1675 published the first book in English that was devoted solely to electrical phenomena.<sup id="cite_ref-Baigrie20_21-0" class="reference"><a href="#cite_note-Baigrie20-21"><span class="cite-bracket">&#91;</span>21<span class="cite-bracket">&#93;</span></a></sup> His work was largely a repetition of Gilbert's studies, but he also identified several more "electrics",<sup id="cite_ref-Baigrie21_22-0" class="reference"><a href="#cite_note-Baigrie21-22"><span class="cite-bracket">&#91;</span>22<span class="cite-bracket">&#93;</span></a></sup> and noted mutual attraction between two bodies.<sup id="cite_ref-Baigrie20_21-1" class="reference"><a href="#cite_note-Baigrie20-21"><span class="cite-bracket">&#91;</span>21<span class="cite-bracket">&#93;</span></a></sup> </p><p>In 1729 <a href="/wiki/Stephen_Gray_(scientist)" title="Stephen Gray (scientist)">Stephen Gray</a> was experimenting with <a href="/wiki/Static_electricity" title="Static electricity">static electricity</a>, which he generated using a glass tube.
