Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge.Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.
In these equations ρ m is the magnetic charge density, j m is the magnetic current density, and q m is the magnetic charge of a test particle, all defined analogously to the related quantities of electric charge and current; v is the particle's velocity and c is the speed of light. For all other definitions and details, see Maxwell's equations.
[27] [28] The simple classical mechanics definition of mass differs slightly from the definition in the theory of special relativity, but the essential meaning is the same. In classical mechanics, according to Newton's second law , we say that a body has a mass m if, at any instant of time, it obeys the equation of motion
Quantum information is the information of the state of a quantum system. It is the basic entity of study in quantum information theory, [1] [2] [3] and can be manipulated using quantum information processing techniques. Quantum information refers to both the technical definition in terms of Von Neumann entropy and the general computational term.
Magneto-inertial fusion begins with a warm dense plasma target containing a magnetic field. Plasma's conductivity prevents it from crossing magnetic field lines. Compressing the target amplifies the magnetic field. [4] [5] [6] Since the magnetic field reduces particle transport, the field insulates the target from the liner.
Non-nuclear electromagnetic pulse (NNEMP) is a weapon-generated electromagnetic pulse without use of nuclear technology. Devices that can achieve this objective include a large low-inductance capacitor bank discharged into a single-loop antenna, a microwave generator, and an explosively pumped flux compression generator.
Magnetic flow meter Electromagnetic flow meter Electromagnetic flow meter. A magnetic flow meter (mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference ...
Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. (Dispersive effects are a property of certain systems where the speed of a wave depends on its frequency.) Solitons are the solutions of a widespread class of weakly nonlinear dispersive partial differential equations describing physical systems.
