... (III) The two strands of the helix-shaped DNA molecule are held together by electrostatic forces as shown in Fig. 16–44. Assume that the net average charge (due to electron sharing) indicated on H and N atoms is 0.2e and on the indicated C and O atoms is 0.4e. Assume also that atoms on each molecule ...

... W e have calculated that the field of an electric dipole for points on the axis of the dipole is given by |E| = (1/4 Bgo)(2qa/x 3), where 2a is the distance between the two charges q, and here the dipole is aligned along the x axis. An electric quadrupole can be treated as two dipoles, head to head, ...

... If you rub a rubber rod with rabbit fur (thus giving the rod a negative charge) and bring the rod near some bits of neutral paper, the rod will attract the bits of paper. Though they remain neutral, the bits of paper do become polarized--the end of a bit of paper closer to the rod becomes positive w ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
