its a hard thing but iam smart
What is the relationship between electrical frequency and magnetic field speed for an ac machine
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.
-- 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.

Surrounding a magnet with a magnetic shell can allow the magnetic field to move farther away from its source.
The further the magnets, the lesser the attraction/repulsion.
the magnetic field gets stronger with increasing distance from the wire
distance is the only insulator
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.
