Is the process of producing an electric current by moving a loop of wire through a magnetic field?
A current is induced in the conductor by the moving magnetic field (relative to the wire, the field is moving) I guess induction might be the term you are looking for.Another AnswerMoving a magnet through a loop of wire will induce a voltage, not a current, into a coil. If the coil forms a closed loop, then a current will result. But it's a voltage that's being induced, not a current -the current is merely the result of that voltage.
What is J4 variac?
A J4 variac is an electronics term. This term refers to the variable amount of wattage in the electric field.
What is induced magnetism?
In the simplest terms, Induced Magnetism is the magnetism of an object as a result of an external influence. Typically, the external influence is a magnetic field due to another object. (One also hears the term transient magnetism applied to the same phenomenon. To be considered transient, the magnetism must disappear when the external influence disappears, but to be "induced" it just has to appear.) Though this is a technical term, it has a meaning that is the normal meaning of "induced," as in "caused by." This is to be contrasted with other modifiers, like "permanent magnetism" or "remnant magnetism" or "spontaneous magnetism" which are all still magnetism of an object but with a modifier further describing the magnetic state. If one is being more technical, then in scientific circles the term "induced magnetism" usually refers the situation where an object acquires a magnetic field as a result of it being in some external magnetic field even though it is not normally a magnetized material. One see this all the time. If you bring a permanent magnet near a collection of paperclips, then the paperclips all attach to one another and to the permanent magnet. Each paperclip has become, temporarily, a magnet. If the permanent magnet is removed, the paperclips no longer attach to one another. The magnetic properties of the paperclips were "induced" and not a permanent characteristic. More technicalities can be present with this term, because magnetism in an object can be induced in other ways than the application of a magnetic field. In the absence of such technical considerations, it is safe to assume that the term "induced magnetism" just means a temporary state of magnetization of an object induced by an external magnetic field provided by a permanent magnet or an electromagnet.
Define the term induced current?
a current can be induced by changing the area of a coil in a constant magnetic field. By Faraday's Law: the induced current is proportional to the rate of the change of flux in a loop of wire. With magnetic flux being defined as the product of the magnitude of the magnetic field and the area of the loop. The direction of the current is found from Len's Law: The induced current produces an induced magnetic field that opposes the change of flux causing the current.CommentYou don't induce a current, you induce a voltage. And Faraday's Law states that the induced voltage, not current, is proportional to the rate of change of flux! If the coil is open circuited, a voltage is still induced into the coil but no current will flow. For current to flow, the coil must be connected to a load (or short circuited), and this current is dependent upon the values of the induced voltage and the resistance of the load.
Lenz's law is in accordance with the law of conservation of energy?
Indirectly. Lenz's Law is a manifestation of the conservation of the Electric field, E.The Electric field is a quaternion fieldE= Er + Ev where Er is the real field Er and Ev is the vector field. E is a quaternion filed the sum of the real Er and the vector Ev.The conservation of the electric field is the boundary condition:0=XE = (d/dr + Del)(Er + Ev) = (dEr/dr - Del.Ev) + (dEv/dr + Del Er + DelxEv)Lenz's law results from:0 = (dEv/dr + Del Er + DelxEv) = dBv/dt + del Erwhere dEv/dr = dEv/cdt = dBv/dt where dr= cdt and E=cB.Lenz's Law is the impact of Del Er the "so-called back emf". This term is missing in Maxwell's Equations Electric field Equations, it is included in thee magnetic Field Equations as Del Hr = J the current density.Maxwell' s Equations are corrected in the above formulation and include the Lenz's law effect directly.
How would you define gauss law?
Gauss's Law states that the total electric flux through a closed surface is proportional to the total charge enclosed by that surface. In simpler terms, it describes how electric charges create an electric field in space.
What physical principle involving electric charges and a magnetic field is employed in the production of an electric current by an electric generator?
The physical principle that produces and electric current by an electric generator is theConservation of the Magnetic field: 0 =(d/dr + Del)(Bs + Bv)The field B is a quaternion field with the scalar part Bs and the vector part Bv.0= dBv/dr + Del Bs + DelxBv = dBv/cdt + Del Bs + DelxBvThis is the vector part (generator) of the Conservation,The magnetic field and electric field are related E=cB thus0= dBv/cdt + Del Bs + DelxBv = dBv/dt + Del Es + DelxEvFaraday did not include the scalar field and the term Del Es is missing from his Law.Del Es is the gradient of the scalar electric field and provides the back emf.The scalar part of the conservation of B is:0= dBs/dr - Del.BvHere too, the scalar filed Bs is left out and scientists declare that Del.Bv is always zero.This too is wrong dBs/dt = Del.Ev = rho/epsilon = zc rho = zJs
What is electrical anharmonicity?
Electrical anharmonicity refers to a term in the potential energy of a crystal which is linear in the externally applied electric field amplitude, and quadratic in lattice displacement coordinates. As such, it gives a dielectric polariztion which is quadratic in the lattice coordinates. Such an interaction term of lattice and external field allows the direct absorption of photons by two-phonon states of the crystal.
What is the definition of the term dielectric?
'Dielectric' is often used in a general sense to refer to a material (such as ceramic, mica, plastic or paper) which is a poor conductor of electricity. This term is used in the classical description of a capacitor -- two electric conductors separated by a dielectric. By applying electric charge to one conductor an electric field is created. The dielectric allows the electric field to pass through it and affect the other conductors; however the dielectric prevents electrons from flowing between the conductors, so the electric field remains (and the charge remains stored on the conductor). [Side note for beginners: An electric field creates a force (measured in Volts) upon an electron or charged particle which tends to make it move. The conductor allows electrons to move easily within it. The dielectric resists the movement of electrons in it.] More generally, we speak of a 'Dielectric Field' as a mathematic description of how electric charge influences the properties of the space around it. The Dielectric field interacts with space and with any material in the space to create an 'Electric Field'. In simple terms, the electric field at any point is the product of the dielectric field at that point and the 'Dielectric Constant' of the material at that point. In more general terms, the 'electric field vector' at a point is the tensor product of the 'dielectric field vector' and the 'dielectric tensor' of the material at that point. The dielectric field is not a measurable entity, but rather a mathematical tool that allows us accurately to model the electric field, which is measurable. The article on Dielectrics at http://en.wikipedia.org/wiki/Dielectric provides more description, especially on the dielectric field model.
