In physics, a Dirac string is a fictitious one-dimensional curve in space, stretched from a magnetic monopole to infinity. The gauge potential cannot be defined on the Dirac string, but it is defined everywhere else. The Dirac string acts as the solenoid in the Aharonov-Bohm effect, and the requirement that the position of the Dirac string should not be observable implies the Dirac quantization rule: the product of a magnetic charge and an electric charge must always be an integer multiple of .

Dirac delta functionThe Dirac delta function introduced by Paul Dirac, can be informally thought of as a function δ x that has the value of infinity for x 0, the value zero elsewhere, and a total integral of one. The graph of the delta function can be thought of as fol	Dirac equationThe Dirac equation is a relativistic quantum mechanical wave equation invented by Paul Dirac in 1928. It provides a description of elementary spin-1/2 particles, such as electrons, that is fully consistent with the principles of quantum mechanics and larg	DiracThis article is about the codec.
