Chapter 23: Electricity and Magnetism
... 23.1 Electric Current and Magnetism The magnetic field around a single wire is too small to be of much use. There are two techniques to make strong magnetic fields from current flowing in wires: 1. Many wires are bundled together, allowing the same current to create many times the magnetic fie ...

Electric Fields ch 26
... To find the e-field of other shapes, break the shape up into little bitsy tiny small pieces, each of which creates an electric field like a point source. By summing these up (integrating) you determine the e-field of the whole shape. Our book goes through the integration for a long charged wire ...

History of electrochemistry
Electrochemistry, a branch of chemistry, went through several changes during its evolution from early principles related to magnets in the early 16th and 17th centuries, to complex theories involving conductivity, electric charge and mathematical methods. The term electrochemistry was used to describe electrical phenomena in the late 19th and 20th centuries. In recent decades, electrochemistry has become an area of current research, including research in batteries and fuel cells, preventing corrosion of metals, the use of electrochemical cells to remove refractory organics and similar contaminants in wastewater electrocoagulation and improving techniques in refining chemicals with electrolysis and electrophoresis.
