This quantity is equal to the opposite of the dot product of the magnetic dipole moment with the magnetic field.
This quantity is equal to the opposite of the dot product of the magnetic dipole moment with the magnetic field. It is subtracted in a Lagrangian [la- grahn-zhee-an] but added in a Hamiltonian. In a central inverse square field, it varies inversely with the distance from the center and is generally assigned a negative value. This quantity is only defined for conservative fields, in which it equals the opposite of the integral of force with respect to distance. Its existence is due to the ability of the system to change the work that has been done to it into another form of energy. In a spring, this value is equal to one-half times the spring constant times the displacement squared, and in a uniform gravitational field it is given as mass times gravitational field strength times height. Name this type of energy an object has by virtue of its position, often contrasted with kinetic energy.
