The magnetic field in an alternator is created by the rotor, which is an electromagnet that produces a rotating magnetic field as it spins. This magnetic field induces an alternating current in the stator windings through electromagnetic induction, which is then converted to usable electrical power.

How is a magnetic field created?
A magnetic field is created when electric charges move. This movement generates a force that aligns the charges in a specific direction, creating a magnetic field around the moving charges.
What creates the magnetic field for the electromagnet?
The magnetic field for an electromagnet is created by the flow of electric current through a coil of wire, which generates a magnetic field around the coil.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
The force field created between the poles of a magnet?
The force field created between the poles of a magnet is called a magnetic field. It arises from the movement of electric charges within the magnet and affects other magnets or magnetic materials within its vicinity. The magnetic field is responsible for the attractive or repulsive forces observed between magnets.
How is a magnetic field created for an electromagnet?
A magnetic field is created in an electromagnet when an electric current flows through a coil of wire. The moving electrons within the wire generate a magnetic field around the coil, resulting in the electromagnet attracting or repelling other magnetic materials. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
What is function of a stator in alternator?
The stator is the stationary winding assembly that makes the magnetic field inside the alternator. It is this magnetic field that the armature rotates in generating the electricity.
Name the types of alternators based on their rotor construction?
1) Rotating armature alternator, rotates in stationary magnetic field. 2) Rotating field alternator, the magnetic field is rotating.
What does the magnetic field in an alternator rotate around?
Stator
What does a stator do on an alternator?
The stator on an alternator is used to generate a magnetic field. This is a large factor in the production of electricity.
Why the field windings are placed in rotor of alternator?
In an alternator, field windings are placed on the rotor to create a rotating magnetic field necessary for inducing electrical current in the stator windings. This configuration allows for a more compact design and enables the use of higher magnetic flux densities, improving the alternator's efficiency. By placing the field windings on the rotor, the alternator can generate a strong magnetic field while keeping the stator stationary, which simplifies the design and minimizes wear on the components. Additionally, this arrangement allows for easier cooling of the rotor and better control of the magnetic field strength.
When was Mercury's magnetic field created?
Mercury's magnetic field was created in 1974-04.
What three things are required to produce EMF in an alternator?
Three things required to produce electromotive force (EMF) in an alternator are a magnetic field, a conductor, and relative motion between the magnetic field and the conductor.
What is rotor in ac alternator?
A Rotor is a mechanism in the alternator that is driven by the pulley belt from the engine.which creates a magnetic field which causes voltage.Answer.The rotor does not 'create' a magnetic field. The emf induced in the stator winding is due to the residual magnetic flux of the rotor which cuts the stator windings as the rotor rotates.
