A magnet field is the area surrounding a magnet within which the effects of that field may be observed.
A magnetic field is represented by imaginary lines of force that we call magnetic flux. Magnetic flux (symbol, the Greek letter phi) is measured in webers (pronounced 'vay-bers'); the intensity of the magnetic flux is called magnetic flux density which is defined as the flux per unit area, measured in webers per square metre, which is given the special name, the tesla.

∙ 8y agoElectric flux is corresponding to the quantity of electric field lines going through a surface perpendicular to the lines. More generally, in the event that the electric field is uniform, the electric flux going through a surface is ES cos theta, where S is the area of the surface, E is the magnitude of the electric field and theta is the angle between the field lines and the normal to the surface.
Magnetic flux is the quantity of magnetic field lines going through a closed surface. The SI unit of attractive flux is the weber (Wb). The CGS unit is the maxwell.

∙ 11y agothe relation between magnetic flux density and applied voltage is proportional..that is why it is said that eddy current loss is proportional to square of the supply voltage

What is the difference between magnetic flux magnetic flux densitymagnetic flux linkage?
light speeeed mofos
How does an electric generator works?
The voltage was produce by cutting of the magnetic flux by the conductors.
How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
Why voltage induced when moving coil cuts flux?
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows

What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.

Why does voltage lead current in an inductor?
From what I've read, an inductor is designed to store energy in the form of a magnetic flux. A simple inductor can be thought of as a coil of wires around a medium. The current causes the flux to go through each turn of the coil. Further examination and Faraday's law leads to this model. v= N * D(magnetic flux) Because the current inside the coil is what generates the flux, the voltage will change first, before the flowing electrons will get all the way through the inductor. The inductance constant L is the Number of turns in the wire times the ratio of the current i to the magnetic flux, which is usually a constant. L = N*flux/i Which leads to this relationship between voltage and current in an inductor: v = L* D(i) The D() function being a derivative. Because the derivative of the current will change before the current actually does, voltage leads current in an inductor.
How do magnets help generator produce electricity?
Magnets would have magnetic flux around. As a coil linked with this magnetic flux is rotated such that the flux would change then an electro motive force is induced. This is the way in which generator functions.
Unit of Magnetic flux?
A unit of magnetic flux is called a Weber.
Why is it important that the core of a transformer pass through both coils?
If it doesn't, you don't have a transformer. The core is where the magnetic flux will pass, which induces voltage on the secondary (voltage applied to the primary winding induces a magnetic flux in the core, which induces a voltage on the secondary winding); If the core is not passed through one coil, it will not induce a voltage in that winding. Leakage flux outside the core can result in some inductive coupling, but the job of the core is to couple the primary winding to the secondary winding.
What does a flux density do in a single phase tramsformer?
Answer for USA, Canada and countries running a 60 Hz supply service.In an AC system the voltage alternates 120 times a second. This alternation causes the magnetic field that surrounds the wire in the primary coil to rise and collapse along with the voltage. This magnetic field is also known as magnetic flux. When the flux collapses and rises in the primary winding of the transformer this flux cuts the secondary coils and induces a current to flow in the secondary winding of the transformer. Depending on the amount of coil turns in the secondary, the AC voltage can be higher (step up) or lower (step down) than the primary voltage.
