Magnetic field — This article is about a scientific description of the magnetic influence of an electric current or magnetic material. For the physics of magnetic materials, see magnetism. For information about objects that create magnetic fields, see magnet. For … Wikipedia
Earth's magnetic field — Computer simulation of the Earth s field in a normal period between reversals.[1] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and… … Wikipedia
Dipole model of the Earth's magnetic field — Plot showing field lines (which, in three dimensions would describe shells ) for L values 1.5, 2, 3, 4 and 5 using a dipole model of the Earth s magnetic field The dipole model of the Earth s magnetic field is a first order approximation of the… … Wikipedia
Magnetic nanoparticles — are a class of nanoparticle which can be manipulated using magnetic field. Such particles commonly consist of magnetic elements such as iron, nickel and cobalt and their chemical compounds. While nanoparticles are smaller than 1 micrometer in… … Wikipedia
Magnetic trap (atoms) — A magnetic trap uses a magnetic gradient to trap neutral particles with a magnetic moment. Although such traps have been employed for many purposes in physics research, they are best known as the last stage in cooling atoms to achieve Bose… … Wikipedia
Magnetic mirror point — In astrophysics, a magnetic mirror point is a point where the motion of a charged particle trapped in a magnetic field (such as the Earth s) reverses its direction. More precisely, it is the point where the projection of the particle s velocity… … Wikipedia
geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… … Universalium
Trapped ion quantum computer — A Trapped ion quantum computer is a type of quantum computer. Ions, or charged atomic particles, can be confined and suspended in free space using electromagnetic fields. Qubits are stored in stable electronic states of each ion, and quantum… … Wikipedia
Near and far field — This article is about the electromagnetic concept. For the mathematical, see Near field (mathematics). Antenna field regions for antennas that are shorter than the wavelength of the radiation they emit, such as the whip antenna of a citizen s… … Wikipedia
Quantum field theory — In quantum field theory (QFT) the forces between particles are mediated by other particles. For instance, the electromagnetic force between two electrons is caused by an exchange of photons. But quantum field theory applies to all fundamental… … Wikipedia
Nuclear magnetic resonance quantum computer — Molecule of alanine used in NMR implementation of quantum computing. Qubits are implemented by spin states of the black carbon atoms NMR quantum computing uses the spin states of molecules as qubits. NMR differs from other implementation … Wikipedia
