The physical principle that produces and electric current by an electric generator is the
Conservation 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 + DelxBv
This is the vector part (generator) of the Conservation,
The magnetic field and electric field are related E=cB thus
0= dBv/cdt + Del Bs + DelxBv = dBv/dt + Del Es + DelxEv
Faraday 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.Bv
Here 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

How can magnets produce an electric current?
When a conducting material is moved through a magnetic field, a current starts to flow in the conductor. This is the principle of the electric generator.
What is a machine that produces electric current?
generator
Why was an electric generator made?
because they because they
A device that turns mechanical energy into electric?
The simplest example is an electric generator.
What is the difference between energy conversion that takes place in an electric motor with the conversion that takes place in a generator?
An electric motor converts electric energy to mechanical energy while a generator converts mechanical energy to electric energy.
What is back motor effect in generator?
When current is induced in the rotating coil in an electric generator then a counter couple acts on the current carrying rotating coil in the magnetic field(in accordance to the principle of dc motor). This counter couple is called back motor effect.
How can magnets produce an electric current?
When a conducting material is moved through a magnetic field, a current starts to flow in the conductor. This is the principle of the electric generator.
Making electricity from wind with motor?
the wind mills rotate and the electric generator fixed in the mill converts mechanic energy into electric energy by the principle of electromagnetic induction
What is the difference between electricmotor and generator?
An electric motor is an AC motor which works with alternating current But Generator is D. C motor that works under the principle of direct current
What are the differences between Plutonium production reactors and Power generator reactors?
Plutonium production energy are designed to produce weapons grade plutonium, not electric energy or heat.
Where can I find information that compares a gas generator versus an electric generator?
A gas generator generates electricity and can be used as a backup in a power outage. I am not certain what you mean by an electric generator. If there was a power outage, how would an electric generator work?
What is the technical principle of a natural gas generator system?
The principal of a natural gas generator system is to use hydrocarbon gases that occur naturally underground, such as methane, as fuel in a generator to produce energy for electrical devices. One can buy such generators from 'Electric Generators Direct'.
When was the generator invented?
the AC electric generator was invente by Nikola Tesla. He invented in the late to early 1800's and 1900's. This idea was recently accepted by scienctists.According to the website linked below, it was invented in 1663.
Is an electric power generator safer than a natural gas powered generator?
You can purchase an electric power generator, but it won't do you much good if the electric goes out. A kerosene or deisel generator would be a better choice.
Electric Generator Benefits ?
When selecting a generator for your home, the electric generator stands out from the competition. Compared to gas generators, electric models take up much less space. This can be any essential feature for those using the generator at a vacation home. The electric generator is easy to install. In most cases, the electric generator will need very little maintenance. No harmful gases are emitted making it the most safe generator on the market today.
What is a hydro electric generator?
Hydro- means water. A hydro-electric generator uses moving water from a river or dam to turn the generator and produce electricity.
How does a Van de Graaff generator build up a static charge?
A Van de Graaff generator operates by transferring electric charge from a moving belt to a terminal, usually, a hollow metal ball. It is an electrostatic generator, similar in principle to what happens when you rub your feet against a carpet and touch your cat!
