What is a inconsistency in ampere s law?
One inconsistency in Ampere's law is that it only holds for steady currents, and does not account for time-varying electric fields or changing magnetic fields. This limitation led to the development of Maxwell's equations, which provide a more complete description of electromagnetism.
What is Electric charge flowing in a steady stream called?
Electric charge flowing in a steady stream is called electric current. It is the rate of flow of electric charge and is measured in Amperes (A).
How does the electromagnet in a generator work?
An electromagnet in a generator works by using an electric current to create a magnetic field. This magnetic field interacts with a rotor, causing it to spin and generate electricity through electromagnetic induction. The continuous rotation of the rotor ensures a steady supply of electrical energy.
Is the magnetic field strength in Figure 1 increasing, decreasing, or steady?
In Figure 1, the magnetic field strength is increasing.
What is the word for the steady flow of electric charges along a path is an electric?
The word is "current."
Can a dc electric field produce magnetic field?
Yes. A steady current will produce a magnetic field, B= uI/r
What are the four Maxwell's equation?
Gauss's law: Electric charges produce an electric field. Gauss's law for magnetism: There are no magnetic monopoles. Faraday's law: Time-varying magnetic fields produce an electric field. Ampère's law: Steady currents and time-varying electric fields produce a magnetic field.

Do transformers use steady magnetic fields to produce an emf in the secondary?
In an AC circuit it is the fluctuation of the sine wave which causes a varying magnetic field which in turn induces a current to flow in the secondary.
What is Electric charge flowing in a steady stream called?
Electric charge flowing in a steady stream is called electric current. It is the rate of flow of electric charge and is measured in Amperes (A).
What is a steady stream of electricity?
electric current
Why does an electric current have a magnetic field?
A current carrying conductor, such as a metal wire, will produce a magnetic field around it because of the motion of charge within the wire itself. This motion produces or sets up a magnetic field around the wire in the form of concentric circles. This electromagnetic effect is described in physics by the Biot-Savart Law, an experimentally deduced inverse-square law. The effect is also described by Ampère's Law, which is derived from the Biot-Savart Law. This law relates magnetic field and current. Also, a magnetic field that is set up by an electrical current will produce a magnetic force. This force depends on the rate of charge transfer and the magnetic field. The force produced by a current-carrying wire depends on the length, the magnetic field, and the current, which is the charge flow per unit of time.

Why three phase induction motor has uniform torque?
The 3-phase currents in the 3 coils of an induction motor will produce a steady rotating magnetic field.
During the first quarter cycle energy is given to an inductor. and the same amount of energy is returned by the inductor during the next quarter cycle .then how is energy stored in inductor?
Well, first of all, nobody ever claimed that the energy is stored 'in the inductor'.The energy is stored in the inductor's magnetic field.Next: When they say that energy is stored, it doesn't necessarily mean that it'sstored like in a box or a jar, and you can fill it up, put it up on the shelf, then comeback and get it in a few days.The energy stored in the magnetic field is steady as long as the current through theinductor is steady. If the current is changing, then the energy in the magnetic fieldis also changing. When the energy in the magnetic field is decreasing, then of coursethe magnetic field is returning some of its stored energy to the circuit, by way of thecurrent.
