What is the relationship between electrical frequency and magnetic field speed for an ac machine
Place a cardboard along the cross-section of wire and hold the cardboard horizontally and put iron powder on it and pass current through the wire...the powder will align itself in shape of magnetic field. Another method you can try is on cardboard place a magnetic compass and the needle will align itself in the path of magnetic field and keep marking the position of needle.
magnetic field
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.

What is the relationship between electrical frequency and magnetic field speed for an ac machine
its a hard thing but iam smart
Magnetic fields are made up by a moving electric charge within which the force of magnetism acts:)
The magnetic field will be perpendicular to the electric field and vice versa.More DetailAn electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge. A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.The electrostatic force between charged particles is an example of this relationship.
There is no relationship between GPS (Global Positioning System) and magnetic fields. The GPS system is based on a network of satellites that provide a reference datum that is based on position, regardless of magnetic field.

well as the name mention production of magnetic field due to rotation. if we consider three identical coils axis physically by120* each and 3 phase supply given then their is the production of aleternating magentic field in each coil
The voltage would depend on the speed of the magnet. It also depends on other factors, e.g. the angle between the magnetic field lines and the movement, and the strength of the magnetic field at that point.
