11Magnetic monopole — It is impossible to make magnetic monopoles from a bar magnet. If a bar magnet is cut in half, it is not the case that one half has the north pole and the other half has the south pole. Inst …
12Magnetic dipole — A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the dimensions of the source are reduced to zero while keeping the magnetic moment constant. It is a magnetic analogue of the electric dipole, but… …
13magnetic resonance — Absorption or emission of electromagnetic radiation by electrons or atomic nuclei in response to certain magnetic fields. The principles of magnetic resonance are used to study the atomic and nuclear properties of matter; two common laboratory… …
14Magnetic helicity — In plasma physics, magnetic helicity is the extent to which a magnetic field wraps around itself . It is a generalization of the topological concept of linking number to the differential quantities required to describe the magnetic field. As with …

17Magnetic energy — and electric energy are related by Maxwell s equations. The potential energy of a magnet of magnetic moment m in a magnetic field B is defined as the work of magnetic force (actually of magnetic torque) on re alignment of the vector of the… …
18Magnetic dipole–dipole interaction — Magnetic dipole–dipole interaction, also called dipolar coupling, refers to the direct interaction between two magnetic dipoles. The potential energy of the interaction is as follows: where ejk is a unit vector parallel to the line joining the… …
19Potential energy — This article is about a form of energy in physics. For the statistical method, see Potential energy statistics. Classical mechanics Newton s Second Law …
20Electromagnetic four-potential — The electromagnetic four potential is a covariant four vector defined in volt middot;seconds/meter (and in maxwell/centimeter in parentheses) as:A {alpha} = left( frac{phi}{c}, vec A ight) qquad left(A {alpha} = ( phi, vec A) ight)in which phi is …
