When the loop of wire in an AC generator rotates halfway, it experiences a change in magnetic flux through the loop. This change induces an electromotive force (EMF) according to Faraday's law of electromagnetic induction, causing an alternating current (AC) to flow. As the loop continues to rotate, the direction of the induced current reverses, resulting in the characteristic alternating nature of the current produced by the generator.
What else can I help you with?
Is slip ring a part attached to each end of the wire loop in an ac generator?
In a very simple, laboratory-type, a.c. generator -yes. In practical generators, the output (armature) windings are part of the stator, so do not rotate and, so, don't require slip rings.

What is slide wire generator?
A slide wire generator is a type of electrical generator that uses a sliding contact to produce an output voltage, typically in a laboratory or educational setting. It consists of a long wire wound in a coil, with a movable contact (or slider) that can tap into the wire at various points. By moving the contact along the wire, the generator can produce different voltage levels based on the length of the wire segment being utilized. This device is often used to demonstrate principles of electromagnetism and voltage generation.
How do you sterilize a wire loop?
To sterilize a wire loop, first, hold the loop with forceps and place it in a flame, such as that of a Bunsen burner, until it glows red-hot. This process incinerates any microorganisms present on the loop. Allow the loop to cool before using it to avoid killing the desired cultures or samples. Always ensure the loop is handled using sterile techniques to maintain its sterility.
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
How does a generator turn kinetic energy into electrical energy?
A generator uses a magnetic field and motion (kinetic energy) to induce an electric current in a wire loop. As the wire loop rotates within the magnetic field, it creates a flow of electrons, generating electrical energy. This process is known as electromagnetic induction.
A device that produces an electric current by rotating a loop of wire in a magnetic field?
This device is called an electric generator. When the loop of wire rotates in the magnetic field, electromagnetic induction occurs, producing an electric current in the wire. Generators are commonly used in power plants to convert mechanical energy into electrical energy.
When the wire loop of a generator turns an electric current is produced?
When a wire loop in a generator rotates within a magnetic field, it cuts through magnetic field lines, inducing an electric current in the wire due to electromagnetic induction. This phenomenon is the basis for generating electricity in power plants, where mechanical energy is converted into electrical energy.
What is the name of a machine that produces electricity by turning a loop of wire in a magnetic field?
A generator.
Why does a generator work?
When a conductive loop is moved through a magnetic field, an electric current is produced in the wire loop. This is the basis of electrical generators.
How does an electric generator generate an electric current The generator?
The rotor turns (rotates) causing magnetic fields to move across a coil of wire. This induces an electrical current in the wires of the coil.
How do you build your own wind powered generator?
Pinwhel connected to a coil of wire that rotates within the magnetic field of a (or 2) permanent magnets.
Is it true or false that in a generator the up-and-down motion of the crank induces a current in the wire?
True. In a generator, the up-and-down motion of the crank rotates a coil of wire within a magnetic field, inducing a current in the wire through electromagnetic induction. This process converts mechanical energy into electrical energy.
A machine that uses a magnet to make electricity is called?
A generator is a machine that uses a magnet to produce electricity. As the magnet rotates within coils of wire, it induces an electric current to flow, generating electrical power.
What is the shape of the loop of wire in the scenario where a loop of wire is in the shape of two concentric semicircles as shown?
The shape of the loop of wire is two concentric semicircles.
What condition will sinusoidal voltage be generated in a coil of wire that rotates in a magnetic field?
a generator or alternator,if the magnetic is permanent the current produced from the coil will be alternating current ac.
How commutator converts AC to DC?
There is no conversion of AC to DC a commutator is the key to creating straight DC voltage. "The commutator rotates with the loop of wire just as the slip rings do with the rotor of an AC generator. Each half of the commutator ring is called a commutator segment and is insulated from the other half. Each end of the rotating loop of wire is connected to a commutator segment. Two carbon brushes connected to the outside circuit rest against the rotating commutator. One brush conducts the current out of the generator, and the other brush feeds it in. The commutator is designed so that, no matter how the current in the loop alternates, the commutator segment containing the outward-going current is always against the "out" brush at the proper time. The armature in a large DC generator has many coils of wire and commutator segments. Because of the commutator, engineers have found it necessary to have the armature serve as the rotor(the rotating part of an apparatus) and the field structure as the stator (a stationary portion enclosing rotating parts). Which is the inverse of an AC Generator."
