75Maxwell's equations — For thermodynamic relations, see Maxwell relations. Electromagnetism …
76Defining equation (physics) — For common nomenclature of base quantities used in this article, see Physical quantity. For 4 vector modifications used in relativity, see Four vector. Very often defining equations are in the form of a constitutive equation, since parameters of… …
77Magnetism — This article is about magnetic materials. For information about objects and devices that produce a magnetic field, see magnet. For fields that magnets and currents produce, see magnetic field. For other uses, see magnetism (disambiguation).… …
78Mathematics and Physical Sciences — ▪ 2003 Introduction Mathematics Mathematics in 2002 was marked by two discoveries in number theory. The first may have practical implications; the second satisfied a 150 year old curiosity. Computer scientist Manindra Agrawal of the… …
79Tesla (unit) — The tesla (symbol T) is the SI derived unit of magnetic field B (which is also known as magnetic flux density ). One tesla is equal to one weber per square meter, and it was defined in 1960[1] in honour of the inventor, physicist, and electrical… …
