Unit 9: Energy, electricity and magnetism
... All magnets have a magnetic field and two opposite poles, which attract, and two like poles, which repel. Magnetite is a naturally occurring mineral with magnetic properties. Magnets can also be produced artificially from some metals (iron, cobalt, nickel and neodymium). Poles: two areas usually at ...

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.
